The Mexican word for "sauce," which can signify cooked or fresh mixtures. Salsa cruda is "uncooked salsa"; salsa verde is "green salsa," which is typically based on tomatillos, green chiles and cilantro. A broad selection of salsas — fresh, canned or in jars — is available in supermarkets today. They can range in spiciness from mild to mouth-searing. Fresh salsas are located in a market's refrigerated section. At home, they should be tightly covered and refrigerated for up to 5 days. Unopened cooked salsas can be stored at room temperature for 6 months; once opened, refrigerate them for up to 1 month.
