The world of chili peppers is vast and vibrant, a kaleidoscope of colors, shapes, and sensations. For anyone stepping into a grocery store or planning a garden, two names consistently rise to the top: the poblano and the jalapeño. These are not just peppers; they are culinary icons, each with a distinct personality and a dedicated following. But when you’re standing in the produce aisle, staring down a bin of dark, wrinkled poblanos and a gleaming pile of green jalapeños, how do you choose? The decision between a poblano and a jalapeño is more than just a matter of heat; it’s about flavor, texture, and the very soul of the dish you intend to create.
This isn’t a battle with a single winner, but rather a deep dive into the characteristics that make each pepper special. Understanding the fundamental differences between a poblano and a jalapeño will empower you in the kitchen, turning you from a casual cook into a pepper connoisseur. We will explore everything from their place on the Scoville scale to their unique flavor profiles, their most celebrated culinary applications, and even how to grow them in your own backyard. So, whether you’re crafting a comforting weeknight meal or an elaborate feast, this comprehensive guide will equip you with the knowledge to confidently select the right pepper for the job. Let’s unravel the delicious mystery of the poblano vs jalapeño.
Getting to Know the Contenders
Before we pit them against each other, it’s crucial to meet each pepper individually. They hail from the same family but live in very different neighborhoods on the flavor map. Understanding their origins and basic biology is the first step in appreciating their roles in the kitchen. The poblano is the gentle giant, while the jalapeño is the fiery, compact sparkplug. Each has a story to tell, a history rooted in rich culinary traditions that have now spread across the globe. Their physical appearance alone tells you much about their inner nature, offering clues to the experience that awaits your palate.
The journey of the poblano and jalapeño from ancient Mesoamerican staple to global supermarket superstar is a fascinating one. They are both members of the Capsicum annuum species, a remarkably diverse group that also includes bell peppers and cayenne. This shared lineage explains some similarities, but centuries of selective cultivation have carved out two very distinct identities. Let’s pull back the curtain and introduce you to each of these remarkable chilies in detail.
Meet the Poblano: The Hearty and Mild-Mannered Giant
The poblano pepper is a cornerstone of Mexican cuisine, beloved not for its fire but for its profound, rich flavor. Named after the state of Puebla, Mexico, this pepper is a fixture in traditional dishes. In its fresh, immature state, it’s a deep, dark green color, almost black in some varieties, with a skin that can be slightly glossy or a bit matte. It’s a large pepper, typically ranging from three to six inches in length and two to three inches wide, with a curved, triangular shape that somewhat resembles a flattened heart. Its size alone makes it a substantial ingredient, one that can be stuffed and served as a main course.
When you bite into a fresh poblano, you’re greeted with a very mild heat that sits comfortably between 1,000 and 2,000 Scoville Heat Units (SHU). For context, that’s just a gentle warmth, often barely perceptible to those accustomed to spicier foods. The real magic of the poblano lies in its flavor profile. It boasts an earthy, slightly bitter taste with subtle notes of dried fruit or rich tea. This complexity makes it much more than just a vehicle for heat; it’s a flavor foundation. When a poblano is dried, it undergoes a magnificent transformation, becoming what is known as an ancho chile. In this form, the flavors deepen and sweeten, developing raisin-like and smoky notes that are essential for moles and other complex sauces.
Meet the Jalapeño: The Bold and Zesty Classic
If the poblano is the gentle giant, the jalapeño is the lively, charismatic friend who always brings the energy. This pepper is arguably the most recognized chili in the world, a symbol of spice that has been embraced by countless global cuisines. Originating from the city of Xalapa (or Jalapa) in Veracruz, Mexico, the jalapeño is compact, sturdy, and typically harvested and sold while still a vibrant green. It’s a smaller pepper, usually two to three inches long, with a plump, cylindrical shape that tapers to a blunt end. Its skin is smooth, waxy, and taut.
The jalapeño packs a much more significant punch than the poblano, registering between 2,500 and 8,000 SHU on the Scoville scale. This places it squarely in the low to medium heat range, but its intensity can vary dramatically from one pepper to the next. The flavor is bright, grassy, and vegetal with a crisp, clean bite. Unlike the deep, earthy tones of the poblano, the jalapeño offers a fresh, almost tangy heat that can brighten up a dish. As it ripens fully, it turns a beautiful, deep red, becoming slightly sweeter and a bit hotter. When smoked and dried, the jalapeño becomes a chipotle pepper, taking on a distinctive smoky, sweet, and spicy character that is utterly unique.
The Great Showdown: A Detailed Comparison
Now that we’ve been properly introduced, it’s time to place the poblano and the jalapeño side-by-side. This is where we move beyond simple descriptions and into a direct, point-by-point analysis of what sets these two peppers apart. The choice between them will fundamentally alter a recipe, so understanding the nuances of their heat, flavor, and physicality is the key to culinary mastery. We will dissect every aspect, from the initial visual impression to the final lingering taste, providing you with a clear framework for making an informed decision every time you cook.
This comparison isn’t about declaring one pepper superior to the other. Such a verdict would be meaningless, as each excels in its own domain. Instead, we will create a detailed profile of their differences, celebrating the unique attributes that make the poblano and jalapeño such invaluable assets to any kitchen. We’ll look at the numbers, the sensations, and the practical applications, giving you a holistic understanding of how these two chilies perform when the rubber meets the road—or rather, when the pepper meets the pan.
Heat Level: The Scoville Scale Showdown
The most obvious and often most important difference between these peppers is their spice level. The Scoville scale is the universal standard for measuring this, and the gap between the poblano and the jalapeño is significant. For the heat-averse or those cooking for a sensitive palate, this is the first and most critical filter. The poblano sits on the very lowest end of the “spicy” spectrum. Its range of 1,000 to 2,000 SHU is often described as a mere whisper of heat, a gentle warmth that tingles the tongue without ever approaching pain. Many people who are sensitive to spice find the poblano to be perfectly palatable, and its heat is easily tamed by removing the seeds and veins.
The jalapeño, on the other hand, is a definitive step up. Ranging from 2,500 to 8,000 SHU, its heat is immediate and pronounced. It’s a crisp, sharp burn that concentrates on the tip of the tongue and the front of the mouth. What’s fascinating—and sometimes frustrating—about the jalapeño is its unpredictability. You can bite into one and experience a mild zing, and then bite into another from the same batch and feel a substantial kick. This variation is due to growing conditions, and it’s part of the pepper’s charm (and danger). A red, fully ripe jalapeño will often be at the hotter end of its range. When comparing the heat of a poblano vs jalapeño, it’s clear that the jalapeño is consistently the spicier option, often by a factor of four or more.
Flavor Profile: Beyond the Burn
While heat gets all the attention, flavor is the true soul of a pepper. This is where the poblano and jalapeño diverge most dramatically, occupying entirely different sensory territories. The flavor of a poblano is deep, complex, and earthy. Think of the taste of a green bell pepper, but richer, more profound, with hints of bitterness and a subtle, almost prune-like undertone. It’s a robust flavor that can form the backbone of a dish, contributing body and a low, resonant warmth rather than a sharp spike. This makes it excellent for sauces, stews, and stuffed peppers where its flavor can meld and deepen with other ingredients.
The jalapeño offers a completely different experience. Its flavor is bright, grassy, and distinctly “green.” It has a fresh, vegetal quality that can cut through rich, heavy foods, providing a welcome burst of acidity and life. The heat it brings is integrated with this bright flavor, creating a zesty, lively sensation. You don’t just add a jalapeño for spice; you add it for a specific kind of vibrant, pungent flavor that awakens the palate. It’s the difference between the deep, comforting notes of a cello (the poblano) and the sharp, clear call of a trumpet (the jalapeño). Both are beautiful, but they play very different parts in the culinary orchestra.
Physical Appearance and Texture
You can easily tell a poblano and a jalapeño apart just by looking at them. The poblano is large, broad, and dark green, with a somewhat irregular, deeply creased surface. It looks substantial, like a pepper built for a purpose. Its skin is thinner than a bell pepper’s but can still be a bit tough, which is why it’s often roasted and peeled. The flesh of a poblano is relatively thick, giving it a meaty, satisfying texture when cooked, perfect for holding a stuffing. Its larger size also means it has a bigger placenta—the white pith inside where the seeds attach—which is the primary source of its mild heat.
The jalapeño is the picture of compact efficiency. It’s smaller, smoother, and boasts a bright, cheerful green color (until it ripens to red). Its shape is uniformly cylindrical, and its skin is thick, waxy, and crisp. When you bite into a fresh jalapeño, you get a satisfying crunch. This texture makes it ideal for salsas, relishes, and raw applications where you want a bit of structural integrity. The flesh is thinner than a poblano’s, and while it can be stuffed, it’s better suited for smaller bites like poppers. The physical contrast between the hefty, wrinkled poblano and the sleek, firm jalapeño is a perfect visual metaphor for their differing culinary roles.
Culinary Uses: When to Use Which Pepper
Your choice in the poblano vs jalapeño debate should be primarily guided by the dish you are making. Their different heat levels, flavors, and textures make them suited for specific, and often non-interchangeable, tasks. Using one in place of the other will not just change the spice level; it will alter the fundamental character of your food. The poblano is your go-to for dishes that require a deep, savory base. Its most famous application is in Chiles Rellenos, where the large, mild pepper is stuffed with cheese or meat, battered, and fried. Its sturdy structure and mild flavor make it perfect for this. It’s also diced and used in soups, stews, and particularly in rajas, the classic Mexican dish of roasted pepper strips simmered with cream and onions.
The jalapeño is the workhorse of fresh salsas, guacamoles, and garnishes. Diced finely, it adds a bright kick and fresh flavor to pico de gallo. Sliced into rings, it’s a classic topping for tacos, nachos, and burgers, providing a crunchy, spicy bite. It’s also the star of the show when pickled, which tames its heat slightly and adds a lovely tang. And of course, it’s the essential ingredient for jalapeño poppers, where its size and shape are ideal for filling with cream cheese, wrapping in bacon, and baking or frying. Trying to make poppers with a poblano would be unwieldy, just as trying to use a jalapeño for chiles rellenos would result in an overly spicy and structurally unsound dish.
Growing and Selecting Your Peppers
For the home gardener or the discerning shopper, knowing how to grow and choose the best poblanos and jalapeños is an extension of the culinary conversation. The journey of these peppers from seed to plate influences their final flavor and heat. Growing them yourself gives you ultimate control and a deep appreciation for their characteristics, while knowing how to select the perfect specimens at the store ensures your culinary creations start on the right foot. Both plants are rewarding to grow, but they have slightly different needs and yields.
Understanding the life cycle of these plants also demystifies some of their variations. Why are some jalapeños so much hotter than others? Why do poblanos sometimes have more heat? The answers often lie in the stress the plant experiences during its growth. Let’s dig into the dirt and explore the horticultural side of the poblano vs jalapeño discussion, and then learn how to pick the champions from the supermarket bin.

In the Garden: A Grower’s Perspective
Both poblano and jalapeño plants are relatively easy to grow in warm climates with plenty of sun, but they exhibit different growth habits. The poblano plant is typically larger and more sprawling. It can reach heights of two to three feet and benefits from staking, as the large, heavy peppers can weigh down the branches. The plant produces a good yield of these substantial fruits throughout the growing season. Poblanos take a bit longer to mature than jalapeños, often requiring 65 to 80 days from transplanting to produce full-sized, dark green peppers. If you leave them on the plant, they will eventually turn red and become slightly sweeter.
The jalapeño plant is generally more compact and bushy, making it an excellent choice for container gardening. It’s a prolific producer, often yielding dozens of peppers per plant. Jalapeños mature more quickly, usually in about 70 to 80 days. One of the most interesting aspects of growing jalapeños is the phenomenon of “corking.” These are small, tan-colored stretch marks that appear on the skin of the pepper. Contrary to what some believe, corking is not a defect; it is often a sign of a particularly hot and flavorful jalapeño. The stress that causes the corking is thought to concentrate the capsaicinoids. For both plants, consistent watering and plenty of sunlight are key, but a little bit of stress from underwatering can actually increase the heat levels in the final fruit.
At the Market: How to Pick the Perfect Pepper
Whether you’re buying poblanos or jalapeños, the principles of selection are similar: look for freshness and health. A high-quality poblano should be a deep, dark green color (or a rich red if you’re seeking a ripe one). It should feel firm and heavy for its size, with a glossy, unblemished skin. Avoid any peppers that are soft, have wrinkled skin, or show signs of dark, mushy spots. The stem should be green and fresh-looking. Because of their thin skin, poblanos can dehydrate and wilt faster than thicker-skinned peppers, so freshness is key. A good, fresh poblano promises that deep, earthy flavor and meaty texture.
When selecting jalapeños, look for a vibrant, uniform green color and a firm, smooth skin. The pepper should feel very solid and crisp, not limp or flexible. Again, avoid any with soft spots, wrinkles, or blemishes. Don’t be afraid of jalapeños with corking (those light brown lines); as mentioned, these are often the most flavorful. The smooth, waxy skin should be taut. The heat level is impossible to judge by sight alone, but some gardeners and grocers claim that peppers with small, fine lines (potential early corking) or a slightly more pointed tip might be hotter, though this is not a guaranteed science. Choosing the best specimens is the first step in winning the poblano vs jalapeño battle in your kitchen.
Preparation and Handling Techniques
How you prepare a poblano versus a jalapeño can significantly impact the final dish, especially regarding heat control. The techniques for handling these peppers are informed by their unique structures. For both, it’s important to remember that the compound responsible for the heat, capsaicin, is most concentrated in the white pith (the ribs) and the seeds. If you want to reduce the heat of either pepper, your first step is always to remove these internal components. However, the methods for unlocking their fullest flavor often differ, involving roasting, charring, or using them raw.
A word of caution for the uninitiated: capsaicin oils can stick to your skin and cause a burning sensation, especially if you touch your eyes or other sensitive areas. It’s a good practice to wear disposable gloves when handling large quantities of hot peppers, particularly jalapeños. Always wash your hands, knife, and cutting board thoroughly with soap and water after prepping chilies. Let’s break down the best ways to prepare these two culinary stars.
Mastering the Poblano: Roasting and Peeling
The classic preparation for a poblano almost always involves roasting. This isn’t just a matter of tradition; it serves a crucial purpose. Roasting a poblano over an open flame—whether on a gas stove, under a broiler, or on a grill—charms the skin, making it easy to peel off. More importantly, this process transforms the pepper’s flavor. The high heat caramelizes the natural sugars, deepens the earthy notes, and imparts a wonderful smokiness that is the hallmark of many authentic Mexican dishes.
The technique is simple. Place the whole poblano directly over the flame, turning it occasionally with tongs until the skin is blistered and blackened all over. Then, immediately transfer it to a bowl and cover it with plastic wrap, or place it in a paper bag. The steam trapped inside will loosen the skin, making it effortless to peel off after 10-15 minutes. Once peeled, you can slit the pepper open, remove the seed pod and veins, and you’re left with a tender, flavorful, and smoky pepper ready to be stuffed for chiles rellenos or sliced into silky rajas. This roasting process is what elevates the poblano from a simple vegetable to a complex ingredient.
Taming the Jalapeño: Slicing, Dicing, and Pickling
Jalapeños are far more versatile in their preparation, often used raw but also fantastic cooked or preserved. For raw applications like salsas, garnishes, or relishes, the goal is a clean, precise cut. Slice off the stem end, then slice the jalapeño in half lengthwise. Using a small spoon or a paring knife, scrape out the white ribs and seeds. The more meticulously you remove this pith, the milder your jalapeño will be. You can then slice it into rings, dice it finely, or chop it roughly, depending on your recipe. Leaving the seeds and ribs in will, of course, maximize the heat.
One of the most popular ways to preserve and transform jalapeños is by pickling. Pickled jalapeños (en escabeche) are a staple condiment. The process involves simmering sliced jalapeños in a brine of vinegar, water, salt, and spices like garlic and oregano. The vinegar brine not only preserves the peppers but also tames their heat slightly and adds a delightful tanginess that pairs perfectly with rich, cheesy, or fatty foods. Another iconic preparation is smoking and drying them to create chipotles, but this is typically a commercial process. For the home cook, simple slicing and pickling are the most common and rewarding ways to handle a jalapeño.
Nutritional Face-Off
In the battle of poblano vs jalapeño, nutrition is an area where both peppers are clear winners. All chili peppers are low in calories and packed with beneficial nutrients, making them an excellent addition to a healthy diet. They are both rich sources of vitamins, particularly Vitamin C, which is a powerful antioxidant, and Vitamin A, crucial for vision and immune function. They also provide a good amount of dietary fiber and various B vitamins. The capsaicin that gives them their heat is also being studied for its potential metabolic and anti-inflammatory properties.
While their nutritional profiles are similar, there are some subtle differences driven by their size and color. The larger size of the poblano means that, per pepper, it will deliver more overall volume of these nutrients. However, when compared by weight, the differences become less pronounced. The specific phytonutrients that give each pepper its color also contribute to their unique health benefits. Let’s take a closer look at the vitamin-packed punch these peppers deliver.
Vitamins and Health Benefits
Both peppers are exceptional sources of Vitamin C. In fact, a single jalapeño can provide a significant portion of your daily requirement, and a poblano, being larger, provides even more. Vitamin C is essential for immune system function, collagen synthesis, and iron absorption. They are also excellent sources of Vitamin A, primarily in the form of beta-carotene, which is important for healthy vision, skin, and cellular communication. Poblanos, with their darker green color, are particularly high in Vitamin A.
The capsaicin in both peppers is more than just a source of heat. It’s been linked to several potential health benefits. It may act as a metabolism booster, slightly increasing the number of calories you burn. It’s also known to have anti-inflammatory properties and may act as a natural pain reliever when used in topical creams. Furthermore, some studies suggest that capsaicin can promote heart health by helping to reduce blood pressure and bad cholesterol levels. Whether you choose the mild warmth of a poblano or the zesty kick of a jalapeño, you’re doing your body a favor by incorporating these nutrient-dense foods into your meals.
The Versatile World of Dried and Smoked Peppers
The story of the poblano and jalapeño doesn’t end with the fresh pepper. Both have celebrated second acts in dried form, where their flavors concentrate and transform into something entirely new and equally essential. Understanding these transformations is a key part of the poblano vs jalapeño narrative. It opens up a whole new dimension of culinary possibilities, from complex, simmered sauces to smoky, spicy condiments. The dried versions are not mere substitutes; they are distinct ingredients with their own unique identities and uses.
This process of preservation is an ancient technique that captures the harvest for use throughout the year. It intensifies the sweetness, deepens the earthy tones, and, in the case of the jalapeño, introduces a profound smokiness. Knowing how to use ancho chiles and chipotles is as important as knowing how to use their fresh counterparts for anyone serious about exploring the depths of Mexican and Southwestern cuisines.
Ancho Chile: The Dried Poblano
When a fresh poblano pepper is dried, it becomes an ancho chile. “Ancho” means “wide” in Spanish, a fitting name that describes the pepper’s broad, flat shape after drying. The process is simple: ripe, red poblanos are left to dry naturally, often in the sun, until they become leathery and dark reddish-brown. This transformation is nothing short of alchemical. The mild heat of the fresh poblano remains, but the flavor profile explodes with complexity. The earthy notes deepen into flavors of raisin, prune, tobacco, and a hint of licorice. It becomes sweet, rich, and slightly fruity.
Ancho chiles are rarely used whole. They are typically stemmed and seeded, then toasted on a hot comal or skillet for a minute until they become fragrant. This toasting wakes up their essential oils. They are then rehydrated in hot water before being blended into smooth, luxurious sauces. The ancho is the backbone of many traditional Mexican moles, adobos, and enchilada sauces. It provides color, body, and a deep, resonant flavor that is the very soul of these dishes. In the debate of poblano vs jalapeño, the ancho represents the poblano’s ultimate expression of depth and complexity.
Chipotle Pepper: The Smoked Jalapeño
The jalapeño undergoes an even more dramatic metamorphosis. When ripe, red jalapeños are smoked and dried, they become chipotle peppers. The name “chipotle” comes from the Nahuatl words chili (pepper) and poctli (smoke). This smoking process, which can take several days, completely transforms the pepper. The bright, grassy heat of the fresh jalapeño is replaced by a deep, smoky, sweet, and spicy flavor profile. Chipotles have a distinctive heat that builds slowly and a rich smokiness that can perfume an entire dish.
Chipotles are most commonly found in two forms: the whole dried chile meco and the chipotle en adobo. The latter is a canned product where the smoked peppers are packed in a tangy, sweet, and spicy tomato-based sauce called adobo. This form is incredibly convenient and versatile. A single chipotle pepper, or a spoonful of the adobo sauce, can add instant depth and a smoky kick to marinades, braises, soups, stews, mayonnaise, and even ketchup. The chipotle is the jalapeño’s answer to the ancho—a testament to how preservation can create an ingredient that is fundamentally different from, and just as valuable as, its fresh origin.
A Tale of Two Peppers in Global Cuisines
While the poblano and jalapeño are deeply rooted in Mexican cuisine, their appeal has gone global. They have been adopted and adapted by chefs and home cooks worldwide, finding their way into fusion dishes and becoming staples in international pantries. The journey of the jalapeño, in particular, is a story of global spice domination, from its iconic status in American Tex-Mex food to its surprising appearances in Asian and European dishes. The poblano, with its milder demeanor, is also making inroads, appreciated for its flavor more than its fire.
This global adoption speaks to the versatility and appeal of these chilies. They are no longer confined to their traditional roles but are instead being used as tools to add specific flavor and heat profiles to all sorts of creative culinary endeavors. Exploring how these peppers are used beyond their homeland provides a fascinating glimpse into the dynamic nature of food culture and the universal human love for a little (or a lot of) heat.
The Jalapeño’s Journey to Stardom
The jalapeño’s path to becoming the world’s most famous chili pepper was paved by the rise of Tex-Mex cuisine. Dishes like nachos, loaded with pickled jalapeños, became bar food staples across the United States. The invention of the jalapeño popper turned it into a party favorite. Its manageable heat level and recognizable name made it a safe, approachable gateway into the world of spicy food for millions. As a result, it became the default “spicy pepper” in many supermarkets outside of Latin America.
Today, you’ll find jalapeños adding a fresh kick to Vietnamese banh mi sandwiches, lending their heat to Indian chutneys, and being pickled and used on top of Japanese takoyaki. Their bright, clean heat is easy to incorporate without overwhelming other delicate flavors. The jalapeño’s small size and sturdy nature also make it ideal for commercial agriculture and shipping, cementing its place as a global commodity. It is the friendly, familiar face of spice for a huge portion of the world.
The Poblano’s Rise as a Flavor Powerhouse
The poblano’s global journey has been quieter but no less significant. While it may not have the instant name recognition of the jalapeño, it is increasingly sought after by chefs and home cooks looking for depth of flavor rather than just sheer heat. Its role in the beloved chiles rellenos has introduced it to a wide audience. As more people discover the complex, smoky flavor of roasted poblanos, they are incorporating them into non-traditional dishes.
You might now find strips of roasted poblano (rajas) folded into creamy pasta sauces, diced in corn chowders for a subtle warmth, or pureed into a flavorful base for a unique twist on hummus. Food enthusiasts are discovering that the poblano offers a sophisticated pepper flavor that can enhance a wide range of cuisines, from Italian to American comfort food. Its ability to add a rich, earthy backbone without making a dish painfully spicy is its greatest asset in the global kitchen.
“The poblano is the bassist in the band—providing the deep, resonant foundation—while the jalapeño is the lead guitarist, slicing through with a sharp, memorable solo.” – A Culinary Enthusiast

Frequently Asked Questions
What is the main difference between a poblano and a jalapeno?
The most significant difference lies in their heat and flavor. In the poblano vs jalapeno comparison, the poblano is much milder, ranging from 1,000 to 2,000 SHU, and has a deep, earthy, slightly bitter flavor. The jalapeno is noticeably hotter (2,500-8,000 SHU) and offers a bright, grassy, and crisp taste. Physically, the poblano is larger and darker green, while the jalapeno is smaller, brighter green, and more compact.
Can I substitute a poblano for a jalapeno in a recipe?
You can substitute them, but be prepared for a very different result. Replacing a jalapeno with a poblano will give your dish much less heat and a deeper, earthier flavor, which might get lost if it’s meant to be a garnish. Substituting a jalapeno for a poblano, like in chiles rellenos, will make the dish significantly spicier and the pepper’s smaller size and thinner walls may not hold the stuffing as well. It’s best to use them for their intended purposes.
Which pepper is hotter, a poblano or a jalapeno?
The jalapeno is consistently and significantly hotter than the poblano. The heat of a jalapeno can be 4 to 8 times greater than that of a poblano. While a poblano offers a gentle warmth, a jalapeno delivers a sharp, immediate kick that is unmistakably spicy, placing it in the low to medium heat category compared to the poblano’s very mild rating.
Are poblano and jalapeno peppers good for you?
Absolutely. Both peppers are excellent additions to a healthy diet. They are low in calories and packed with vitamins, particularly Vitamin C and Vitamin A. The capsaicin that gives them their heat is also associated with potential health benefits like boosting metabolism and having anti-inflammatory properties. Whether you choose the mild poblano or the spicier jalapeno, you’re adding a nutrient-dense food to your meal.
How do I reduce the heat of a jalapeno?
To reduce the heat of a jalapeno, you need to remove the source of the capsaicin: the seeds and the white pith (ribs) inside the pepper. Slice the jalapeno in half lengthwise and use a small spoon or paring knife to scrape out all the white membrane and seeds. The more thoroughly you clean this out, the milder the pepper will be. Remember, the flesh of the pepper itself still contains some capsaicin, but the vast majority is concentrated in the pith and seeds.
