Garnish

1. (v.) To add a (typically edible) decorative element to a plate of food prior to serving. 2. (n.) The edible decorative element itself. Parsley is a common garnish.

A garnish is an item or substance used as a decoration or embellishment accompanying a prepared food dish or drink.[1] 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.[2] 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."

The difference between garnish and decoration, is garnish is edible. Plastic grass for sushi presentation is considered a decoration, not a garnish.
