Role in Mexican Spicy Candy

Mexican hot chiles are commonly used in some types of Mexican spicy candy. These chiles, such as habanero, ancho, or other spicy varieties, are used to create a spicy and savory element in certain Mexican candies.

For example, some tamarind candies are made by combining tamarind pulp with chili pepper, creating a sweet, sour, and spicy treat. Additionally, some chili-coated candies, such as chili-covered gummies or dried fruit snacks, may incorporate ground or powdered hot chiles to achieve their spiciness.

If you’re looking for candies with a particular level of heat, it’s a good idea to check the product’s description or packaging to understand the spiciness level before trying them.

Dairy and citrus elements can help neutralize the burn.

These are just a few examples of the many dishes where hot chiles play a central role in Mexican cuisine.

In fact, as an example, chili con carne a well known dish the world over, which is a hearty and flavorful Mexican dish, is also made using hot chiles.

However, the amount and type of chiles used can be adjusted to suit different heat preferences, making it milder or hotter as desired. The heat from the chiles, combined with other ingredients like ground meat, beans, tomatoes, and various seasonings, creates a savory and satisfying chili stew.

Is Ancho Chile a Mexican Hot Chile?

Ancho chile is indeed a type of hot chili pepper used in Mexican cuisine, but it is not one of the spiciest varieties.

On the Scoville Heat Scale, which measures the spiciness of chili peppers, ancho chiles typically range from 1,000 to 2,000 Scoville Heat Units (SHU). This makes them considerably milder than some of the hotter Mexican chile peppers like jalapeños (2,500-8,000 SHU) or habaneros (100,000-350,000 SHU).

Despite their mild heat, ancho chiles are prized in Mexican cuisine for their rich, fruity, and slightly smoky flavor. They are commonly used in various dishes, especially for making sauces like mole and adobo, where their flavor is more important than their heat. Ancho chiles can add depth and complexity to Mexican recipes without overwhelming them with spiciness.

Recent Popularity of Guajillo

Guajillo chiles typically have a Scoville Heat Unit (SHU) rating that ranges from 2,500 to 5,000, making them somewhat hotter than the poblano pepper but milder than some of the spicier varieties like habaneros or serranos. They are known for their slightly fruity, tangy, and smoky flavor, which adds complexity to many Mexican dishes.

Guajillo chiles are commonly used to make red sauces, including mole, adobo, and various salsas, where they contribute both color and a moderate level of heat. They are an essential ingredient in Mexican cuisine and play a significant role in defining the flavor profiles of many traditional dishes.

Chipotle Process

On the Scoville Heat Scale, chipotles typically range from 2,500 to 8,000 Scoville Heat Units (SHU), depending on factors such as the variety of jalapeño and the drying process.

Chipotle peppers have gained significant popularity in modern cuisine, both in Mexico and around the world, due to their unique flavor profile. They are used in a variety of dishes, including sauces, marinades, salsas, and even in barbecue and Tex-Mex cuisine.
