If you’re a fan of Mexican cuisine, you may have come across chile negro and guajillo peppers while preparing your favorite dishes.

While both are popular ingredients in Mexican cooking, they have some distinct differences that can affect the flavor and heat level of your dish.

In this article, we’ll explore the differences between chile negro and guajillo peppers and help you decide which one to use in your next recipe.

One of the most noticeable differences between chile negro and guajillo peppers is their heat level. Guajillo peppers can be quite hot, with a Scoville rating of up to 5,000, while chile negro peppers only reach up to 2,500 SHU.

Another difference is their appearance, with chile negro peppers being longer and thinner than guajillo peppers.

Despite these differences, both peppers are often used in similar ways in Mexican cuisine, and can be used to add depth and complexity to a wide range of dishes.

What Is Chile Negro?

Chile negro, also known as pasilla pepper, is a dried chili pepper commonly used in Mexican cuisine. It is a long, dark brown to black pepper with a wrinkled texture and a mild, earthy flavor. The name “pasilla” means little raisin, which refers to the pepper’s raisin-like appearance after being dried.

Chile negro peppers are typically harvested when they are still green, then dried in the sun until they turn dark brown or black. They are often used in mole sauces, stews, and soups, as well as in marinades and rubs for meats.

While chile negro peppers are not as spicy as some other varieties, they still pack a bit of heat, ranging from 1,000 to 2,500 on the Scoville scale. This makes them a good choice for those who want to add flavor without too much heat.

What Is Guajillo?

If you are a fan of Mexican cuisine, you have probably come across the guajillo pepper. Guajillo peppers are a type of dried chili pepper that is commonly used in Mexican cooking. They are an essential ingredient in many traditional Mexican dishes, including mole sauce, enchiladas, and tamales.

Guajillo peppers are long, skinny, and have a deep red color. They are typically around 1 inch wide and 3-5 inches long. The skin of the guajillo pepper is smooth, and the flesh inside is thin and slightly sweet. Guajillo peppers have a medium level of heat, which is similar to a mild jalapeño pepper. On the Scoville scale, guajillo peppers have a heat rating of 2,500 to 5,000 SHU.

When you use guajillo peppers in your cooking, you will notice that they have a complex flavor profile. They are slightly fruity, with a hint of smokiness and a touch of sweetness. Guajillo peppers also have a slightly nutty taste, which makes them a great addition to many different types of dishes.
