The Guajillo pepper is a 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. Guajillo peppers have a sweet, tangy flavor with hints of berry and are often used in salsas, sauces, and marinades. These peppers are a key ingredient in traditional dishes like mole and adobo. They can be rehydrated in hot water before use or ground into a powder for seasoning. Guajillo peppers are also rich in vitamins A and C, making them a nutritious addition to meals.
