Nature's Flavors Nectarine Flavor Concentrate contains a very rich and full-bodied flavor. It is very strong, so a little goes a long way. Nectarine Flavor is excellent for baked goods at about 1 to 5% usage, depending on how hot and long you bake it for. It is also good in ice cream, sorbets, icees, shakes, sauces, beverages, puddings, and yogurts.
