This green sauce comes in subtypes: cooked sauce, in which the ingredients are cooked and then ground; roasted salsa, in which the elements are roasted on a comal and then ground; raw sauce, in which ingredients are ground and eaten without cooking; and a combination in which some of the elements are cooked. A molcajete or a blender can be used for the grinding process. Cooking or roasting the tomatillo will enhance the flavor, providing a sweeter salsa.[2] After the sauce is prepared, it can be cooked again in a pan with a little oil.
