Hazelnut
Hazelnuts are nuts of the hazel genus of tree; they are also called cob nuts and filbert nuts. Filbert nuts are more elongated (twice as long as they are round). These nuts fall from their husks when ripe (that is, seven to eight months past pollination). Hazelnuts are oftentimes used as livestock feed or ground into paste. Hazelnut is produced especially in Greece, Turkey, Italy and the U.S. states Washington and Oregon. Hazelnuts are also used alongside chocolate for chocolate truffles.
