Dried Zante grapes called dried currants are used as a snack food or in cereals, stuffings, muffins or other baked goods. Not related to the fresh berry also called a currant.
Some recipes suggest plumping the dried currants before use. You can do this by placing the currants in a small bowl covered with water or even sherry or brandy and allow to sit for at least 30 minutes. Drain the dried currants well before use and discard the soaking liquid unless your recipe states otherwise.
