The combination of unique texture and sweet, tart flavor has made grapes an ever popular between-meal snack as well as a refreshing addition to both fruit and vegetable salads.Grapes are small round or oval berries that feature semi-translucent flesh encased by a smooth skin. Some contain edible seeds while others are seedless. Like blueberries, grapes are often covered by a protective, whitish bloom. Grapes that are eaten as is or used in a recipe are called table grapes and as opposed to wine grapes (used in viniculture) or raisin grapes (used to make dried fruit).
