In fact, raisins are dried fruits, which we consume along with nuts, but we also use them in many sweets and meals. There are two types of raisins, the blonde (sultana) and the black (Corinthian). Black raisin is undoubtedly one of the most important Greek super foods. The best raisins are those that are soft, but not so soft that they stick together. They are rich in vitamin C, folate, iron and fiber.
