Tomatillos have a vibrant, tart flavor with citrus undertones, and they are the key ingredient in dozens of Mexican green sauces. If you've ever had Enchiladas Suizas or Salsa Verde then you're already familiar with the flavor of tomatillos!
Tomatillos can generally be used in similar ways to regular tomatoes, although they offer a slightly more tart flavor and contain less sugar. That tart, slightly acidic taste makes them perfect for use, either raw or cooked, in salsas, sauces, or even jams. When used in salsa, Tomatillos tone down the hotness of chilies and help blend the flavors of the different ingredients. They are credited as the source of the "piquant" flavor in authentic Mexican cuisine, and the slightly immature green fruits are used as the key ingredient for traditional salsa verde, which can be served with just about anything from enchiladas and quesadillas to fried chicken and more. Diced raw Tomatillos also add a nice crunch to fresh guacamole, and they pair well with onions, cilantro, chili peppers and garlic. When harvested at their more ripe, golden-colored stage, they are often used in stews or simmered with meats for flavoring. To prepare the Tomatillo for use in your recipe, remove the papery husks, then rinse and dry the fruit. Tomatillos typically are not seeded before use in cooking. Store Tomatillos with their husks intact for about three weeks in the refrigerator in a paper bag. If you wish to keep them longer, you can remove the husk, wash the fruit, and freeze them.
