Step-by-step explanation:
The question is asking about types of salsas that are based on tomatillos, which are a key ingredient in many Mexican cuisines. Two well-known salsas that include tomatillos as their base are Salsa Verde and Salsa de Tomatillo. Salsa Verde, or green sauce, is made primarily of tomatillos along with ingredients such as chili peppers, onions, cilantro, and garlic. It is known for its tangy and slightly tart flavor.
