We use only the thin outer layer of tree-ripened oranges to make Spice Islands Orange Peel. Orange Peel can be used as a substitute wherever fresh peel is desired. Add Orange Peel to cake, muffin, waffle, pancake, French toast and quick bread batters. Stir into warmed syrups and marinades for a bright, lively flavor. 1 tsp. = 1 tsp. fresh orange peel.
