Tomatillos are also known as Mexican Husk Tomatoes. This fruit originated in Mexico, where they're commonly used to make Chili Verde, Roasted Tomatillo Salsa, and other tasty dishes. Tomatillos are not spicy, but rather taste more like an unripe sour tomato. The texture is denser and less juicy than a tomato. The outer, dry husk is removed to reveal a bright green tomatillo, that loses its brightness when cooked.
