Marinades add exciting flavor to meat, poultry, fish, seafood and vegetables! Mix marinades and marinate in glass or plastic containers or heavy plastic food-storage bags because these containers won’t react with acid ingredients like vinegar, wine or lemon juice. Plan on using 1/4 to 1/2 cup marinade for each 1 to 2 pounds of food. You can marinate all foods except fish in the refrigerator up to 24 hours; if you let it marinated longer, food can become mushy. Marinate fish only 15 to 30 minutes or it will become mushy.
