Finnish cuisine is notable for generally combining traditional country fare and haute cuisine with contemporary continental style cooking. Fish and meat play a prominent role in traditional Finnish dishes in some parts of the country, while the dishes in others have traditionally included various vegetables and mushrooms. Refugees from Karelia contributed to foods in other parts of Finland. Finnish foods often use wholemeal products (rye, barley, oats) and berries (such as blueberries, lingonberries, cloudberries, and sea buckthorn). Milk and its derivatives like buttermilk are commonly used as food, drink or in various recipes. Various turnips were common in traditional cooking, but were replaced with the potato after its introduction in the 18th century.
