Raw Hazelnmut also known as cobnuts or filberts, hazelnuts are good eaten raw but the flavour takes on a more mellow, sweeter character when they are roasted. Like almost all nuts, they have a high fat content, which means they'll go rancid pretty quickly if not refrigerated.
Raw as a snack, or added to muesli. Chopped and used in cakes or crumble toppings. Ground finely to make flour for baking.
