Cooking with Chiles de Arbol
Chile de arbol peppers can be used in any dish to add heat and spice, especially chili, salsa, and hot sauces. It usually only takes a few peppers added to a pot for significant heat. One of the most popular recipes using these peppers is chile de arbol salsa, which can be made from either fresh or dried chiles.
I have personally grown these peppers in my garden and have made chile de arbol salsa with both fresh and dried, and it is difficult to choose a favorite. Each offers its own special quality. Both are delicious as a salsa roja for drizzling over tacos, burritos, tortas, eggs like huevos rancheros and more.
I also enjoy using chiles de arbol for making hot sauce because of their nice level of heat. I prefer more of a vinegary style hot sauce with them, similar to a tabasco sauce, perfect for punching up any meal.
When working with dried chile de arbol peppers, you can either grind them into chili powders or flakes and use them as a seasoning, or rehydrate them by soaking them in very hot water for 15-20 minutes until they are soft, then process them with other ingredients to make a fresh chile de arbol salsa or sauce.

Dried peppers last a long time, though they do eventually lose some of their overall flavor. If you buy them in bulk, which I often do, store them in bags and keep them in a dark place, such as a pantry, away from direct sunlight. The flavor will last longer this way.
