Dried black currants are a powerhouse of nutrition. They are low-fat, cholesterol-free and high-protein, with each cup of dried currants containing 5.88 grams of protein. Dried currants are also an excellent source of nutrients that are essential for health, including dietary fiber, copper, manganese and potassium. The black currant berries have an intense sour flavor and can be either enjoyed raw or used to cook both sweet and savory dishes. Because of their tart taste, many prefer to sweeten them up a bit if eaten raw by using a natural sweetener. They can also be brewed into black currant tea or used to add a unique flavor to juices, jams, sauces, shakes and baked goods.
