🔥 How Hot Are Guajillo Peppers?

Let’s cut right to the chase: guajillo peppers range from 2,500 to 5,000 Scoville Heat Units (SHU). For context:

• Jalapeño peppers = 2,500 – 8,000 SHU
• Serrano peppers = 10,000 – 23,000 SHU
• Guajillo peppers = 2,500 – 5,000 SHU

So, guajillos are actually on the milder side compared to many other chiles used in Mexican cooking. They bring more flavor than fire, making them perfect for those who enjoy depth without overwhelming heat.

💡 Pro Tip:

The spiciness can vary depending on how mature the pepper is when harvested and how it’s prepared. If you're using whole dried guajillos, removing the seeds and veins will further reduce the heat.

🌶️ What Do Guajillo Peppers Taste Like?

Flavor-wise, guajillos offer a complex profile that's hard to beat. Think of them as the unsung heroes of Mexican sauces and moles. Here’s what you can expect:

• Tangy and slightly fruity
• Earthy undertones
• Hint of smokiness
• Berry-like notes (yes, really!)

This unique blend of flavors makes guajillos incredibly versatile in the kitchen. They’re often toasted before rehydrating to unlock more depth — a trick we’ll dive into later.

🍴 Common Culinary Uses

Guajillo peppers are a staple in traditional Mexican cooking. Here are some of the most popular ways they're used:

• Red Enchilada Sauce: One of the most classic uses. Blend soaked guajillos with garlic, spices, and tomatoes for a rich sauce.
• Mole: Often combined with other chiles and spices to create that iconic dark, complex sauce.
• Marinades: Ground guajillo powder adds warmth and color to meats, especially pork and chicken.
• Salsas & Pastes: Great for salsas rojas and adobo pastes.

🧄 How to Work With Guajillo Peppers

If you're new to using dried chilies, don’t worry — guajillos are a great starting point. Here's how to use them like a pro:

1. Rinse them: Give them a quick rinse under warm water to remove any dust or debris.
2. Toast them: Toast in a dry skillet over medium heat for about 30 seconds per side. This enhances their flavor significantly.
3. Rehydrate them: Soak in hot water for 20–30 minutes until soft. Discard soaking water afterward unless you want extra chili flavor in your dish.
4. Blend them: Add soaked peppers to a blender with garlic, vinegar, spices, and a bit of liquid. Puree into a smooth paste or sauce.
