The word hazelnut is sometimes used interchangeably with the word filbert, and they are related, but the two grow on trees of different species.Moreover, there are certain types of hazelnuts that are actually hybrids of filberts and hazelnuts.ike filberts, hazelnuts can be eaten raw or roasted. Hazelnuts have a hard exterior shell, and the nuts themselves have an outer skin which can have a bitter flavor. This outer skin on the hazelnut can removed by blanching the nut. Also Known As: 1  Filbert.
The strongly flavored hazelnut oil is used as a cooking oil. Hazelnut butter is considered as a pleasant and nutritious spread and hazelnut is also popular as a flavoring agent for coffee, especially in the form of hazelnut latte. Hazelnuts generally ripen in late August, which is the best time to find the flavorful nuts. Most grocery stores carry hazelnuts year round, often unshelled and raw. Hazelnuts are also sometimes sold preserved in their own oil. The hazel tree is a fast growing deciduous shrub which produces catkins, which open in the spring. The catkins mature into groups of as many as five nuts, often hidden under the serrated green leaves.
