The Ultimate Chili Pepper Guide
Chili peppers are a cornerstone of Mexican cuisine, adding a wide range of flavors and heat to countless dishes. While many people think of them as vegetables, they are actually fruits because they grow from flowers and contain seeds. This guide will help you understand the different types of chili peppers, both fresh and dried, and how to use them in your cooking.
Understanding the Heat: The Scoville Scale
The heat of a chili pepper is measured in Scoville Heat Units (SHU), which indicates the concentration of capsaicin, the compound responsible for the spicy sensation. The higher the number, the hotter the pepper. Here’s a quick look at where some popular peppers fall on the scale:
- Bell Pepper: 0 SHU
- Pimento: 100–500 SHU
- Jalapeño: 2,500–8,000 SHU
- Cayenne Pepper: 30,000–50,000 SHU
- Habanero: 100,000–350,000 SHU
- Pure Capsaicin: 15,000,000–16,000,000 SHU
A Guide to Fresh Chili Peppers
Fresh chili peppers are vibrant and full of flavor. The most common varieties you’ll find in grocery stores and farmer’s markets include:
- Jalapeño: One of the most popular peppers, jalapeños are typically harvested when green and unripe. When fully ripened, they turn red and can be sweeter and hotter. They’re great for salsas, pickling, and stuffing.
- Serrano: These small, dark green or red peppers look similar to jalapeños but are significantly hotter. They’re a favorite for adding a spicy kick to fresh salsas and sauces.
- Poblano: Mild and earthy, poblanos are large, dark green peppers often used for stuffing in dishes like Chiles Rellenos. When dried, they become ancho peppers.
- Habanero: A powerhouse of heat, habaneros are small and range in color from orange to red. Their fruity, floral flavor is intense, and a little goes a long way.
- Anaheim: Mild and long (6–10 inches), these green peppers are versatile and can be used in many recipes.
- Shishito: These long, thin, and mild peppers are best known for being “lucky”—most are mild, but a small percentage are surprisingly hot. They are often pan-fried and served as an appetizer.
- Pequin: Also known as “bird peppers,” pequins are tiny but pack a significant punch. They are a key ingredient in many hot sauces, including Cholula.
A Guide to Dried Chili Peppers
Dried chiles are essential for deep, complex flavors in Mexican cooking. Drying a pepper concentrates its flavors, often bringing out a smoky or earthy character. Many dried chiles are simply the ripened, dried version of a fresh one. Here’s a breakdown of common types:
- Ancho: The dried form of a ripe, red poblano pepper. Ancho peppers are mild with a sweet, smoky flavor and are a staple in mole sauces and stews.
- Chipotle: These are smoked and dried red jalapeños. They have a distinct smoky flavor and moderate heat, making them perfect for salsas, marinades, and sauces.
- Chile de Árbol: Meaning “tree chili,” this small, thin, and very spicy pepper has a similar flavor profile to cayenne. It’s often used in salsas and sauces for a bright, fiery heat.
- Guajillo: Made from dried Marisol peppers, guajillos are thin, dark red, and have a fruity, tangy flavor with mild to medium heat. They are a common base for sauces, especially adobos and moles.
- Pasilla: The dried version of the chilaca pepper, pasillas are long, dark brown, and have a rich, earthy flavor with mild heat. They’re often used in mole sauces and other deep, savory dishes.
- Cascabel: These dried bola peppers are round and have a mild, nutty flavor. Their name means “rattle” because the seeds inside make a rattling sound when shaken.
Using Chili Peppers in Your Cooking
Chili peppers can be used in countless ways, adding flavor, heat, and color to your dishes.
Ways to Use Them:
- Salsas: Both fresh and dried chiles are the foundation of countless salsas.
- Sauces: Create rich, complex sauces like moles, adobos, and enchilada sauces.
- Stews and Soups: Add depth and warmth to stews and soups.
- Pickling: Preserve fresh peppers to add a tangy, spicy bite to tacos, sandwiches, or salads.
- Spices: Grind dried chiles to create your own chili powder for rubs and seasonings.
A quick tip: For every 4 ounces of fresh peppers, you can substitute 1 ounce of dried peppers or 3 tablespoons of chili powder.
