Filberts, also known as hazelnuts, are small, round nuts that grow on the hazel tree. They have a smooth, brown shell and a rich, slightly sweet flavor. Filberts are commonly used in various culinary dishes, including desserts, snacks, and spreads like Nutella. They are also enjoyed raw or roasted. These nuts are packed with nutrients, including healthy fats, vitamins, and minerals. They are a good source of vitamin E, magnesium, and antioxidants, which can contribute to heart health and overall well-being. Filberts can be found in grocery stores, often sold whole, chopped, or ground into flour.
