A condiment is a spice, sauce, or preparation that is added to food, typically after cooking, to impart a specific flavor, to enhance the flavor, or to complement the dish. A table condiment or table sauce is more specifically a condiment that is served separately from the food and is added to taste by the diner.
Condiments are sometimes added prior to serving, for example, in a sandwich made with ketchup, mustard or mayonnaise. Some condiments are used during cooking to add flavor or texture: barbecue sauce, compound butter, teriyaki sauce, soy sauce, and marmite and sour cream are examples.
Many condiments, such as mustard or ketchup, are available in single-serving packets, commonly when supplied with take-out or fast-food meals.
