Briefly rinse the chile under cold water and pat it dry. Seed and Dice
the chile and add it to the bowl. You can also roast
the chiles for a smokier flavor. Use one jalapeño for mild salsa or 2-3 jalapeños or one serrano chile for medium salsa. For hot salsa, use 5 jalapenos or 2-3 serrano chiles. For extra hot salsa, use one habanero. For mild chile, use an Anaheim chile or a Poblano. They are large chiles, so you may only need half. Here is a Guide to Green Chiles
if you need help selecting one.
