Cobnut

These wild nuts grow in clusters on the hazel tree in temperate zones around the world and the fuzzy outer husk opens as the nut ripens, revealing a hard, smooth shell, also called filberts and cobnuts, particularly when cultivated, these sweet, rich, grape-size nuts are used chopped, ground and whole in all manner of sweets, and they also add flavor and texture to savory items such as salads and main dishes.
