A garnish is an item or substance used as a decoration or embellishment accompanying a prepared food dish or drink. In many cases, it may give added or contrasting flavor. Some garnishes are selected mainly to augment the visual impact of the plate, while others are selected specifically for the flavor they may impart. This is in contrast to a condiment, a prepared sauce added to another food item primarily for its flavor. A food item which is served with garnish may be described as being garni, the French term for "garnished."

A condiment is a preparation that is added to food, typically after cooking, to impart a specific flavor, to enhance the flavour, 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.
