To soak a food such as meat, fish or vegetables in a seasoned liquid mixture called a marinade. The purpose of marinating is for the food to absorb the flavors of the marinade or, as in the case of a tough cut of meat, to tenderize. Because most marinades contain acid ingredients, the marinating should be done in a glass, ceramic or stainless-steel container never in aluminum. Foods should be covered and refrigerated while they’re marinating. When fruits are similarly soaked, the term used is macerate.
