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