26 Interesting Facts about Hazelnuts

Hazelnuts, also known as filberts or cobnuts, are the edible nuts of the hazel tree (Corylus). These small, round nuts have a hard, woody shell that encases a sweet and rich-tasting kernel. Hazelnuts are widely cultivated for both commercial and culinary purposes, prized for their flavor, texture, and nutritional value.

Hazelnut trees are native to regions of Europe and Asia but are now cultivated in various parts of the world, including the United States, Turkey, and Italy. The trees thrive in temperate climates and well-drained soil, producing clusters of nuts enclosed in leafy husks.

They add a delicious nutty flavor and crunchy texture to desserts such as cakes, cookies, and chocolates. Hazelnut flour, made by grinding roasted hazelnuts, is also a popular gluten-free alternative in baking.

In addition to their culinary uses, hazelnuts are prized for their nutritional benefits.
