Guajillo Powder

Part of the Mexican "Holy Trinity" of chili peppers commonly used in mole sauce, guajillo peppers have a sweet, slightly smoky flavor and a relatively moderate kick. It ranges from 2,500 to 5,000 on the Scoville scale - about the same heat as a jalapeño pepper. 

Use guajillo powder for more than mole sauces - it's also delicious in salsas, rubs, soups, and many Mexican meals.
