Guajillo chili is a popular dried chili pepper commonly used in Mexican cuisine. It is known for its deep red color and mild to medium heat, typically ranging from 2,500 to 5,000 Scoville Heat Units. The flavor profile is rich and slightly fruity, with hints of berry and a touch of smokiness, making it a versatile ingredient in sauces, salsas, and marinades. These chilies are often rehydrated before use, allowing them to release their full flavor. Guajillo chilies are a key component in traditional dishes like mole and adobo, contributing to the complex flavors that characterize Mexican cooking.
