Hatch chiles can be mild or very hot, but all varieties are typically roasted before consumption. Roast chiles on a hot grill until the skin blisters. Avoid heating the entire chile. Each side takes about three minutes. Remove the chiles from the grill, and place them in a plastic bag. Seal the bag, and allow it to sweat for about five minutes. This makes the skin easier to remove.
Run the chiles under cool water, pop off the stem, and remove the skin. Once done, the chiles can be chopped to use in cooking or frozen for later. Frozen Hatch chiles keep up to a year.
