Serrano	10,000–23,000 SHU
Hatch Green Chile	1,000–15,000 SHU
Guajillo	2,500–5,000 SHU
Ancho/Poblano	1,000–2,000 SHU
Chipotle	5,000–10,000 SHU
Chile de Árbol	15,000–30,000 SHU
Habanero	100,000–350,000 SHU

Pro Tips for Handling and Using Mexican Peppers Like a Pro

1. Wear gloves when handling hot peppers. Capsaicin can irritate skin and eyes.
2. Remove seeds and membranes for less heat. Most of the spiciness is concentrated there.
3. Roast peppers for deeper flavor. Especially great for poblanos, serranos, and jalapeños.
4. Store dried peppers in a cool, dark place. They last months if kept dry.
5. Soften dried peppers before using. Soak in hot water for 20–30 minutes or toast lightly first.
6. Use vinegar or citrus to balance out the heat. A splash of lime juice can do wonders.
7. Add at different stages of cooking. Add earlier for infused background heat; later for a sharper kick.

Roasting brings out the best in peppers — charred perfection
