After drawing the heat out of the chili peppers, soak them in water with vinegar or salt. This helps chili peppers retain their spicy flavour. The most commonly used chili pepper in Mexican dishes is the jalapeño, a popular fat and green chili pepper.
Using a clay griddle, chili peppers are dry-roasted without using any water or oil. It is usually used to process chili peppers for tortillas.

Chili peppers are charred directly on fire. Once they completely dry out, remove the skin and scrape out the seeds, then blend them together to create the chili powder. The poblano is usually used in this method due to its mild hot level of spiciness.
