A type of tree nut with a shiny, brown exterior and a lighter brown interior. Hazelnuts are earthy in flavor.
Native to Europe, North America, the Middle East, and west Asia.
British colonists introduced European hazelnut trees to North America in 1629.
Another name for hazelnut is “filbert.” The distinction can be made based on whether the hazelnut is wild (called a hazelnut) or cultivated (called a filbert).
