Question: are guajillo peppers spicy hot?
Answer: Once dried, the guajillo chile becomes deep red and develops a tough, smooth skin. Guajillos are medium-sized chiles ranging from 2 to 4 inches in length. It has medium to hot heat (5,000 to 15,000 on the Scoville scale), although if you are not used to hot chiles at all, you might even consider them hot.
