Where It Grows
Hazelnuts, also known as filberts, are primarily grown in regions that have mild, moist climates. The largest producer of hazelnuts in the world is Turkey, producing approximately 75% of the world's total. Other major producers include Italy, Spain, and the United States, specifically in the state of Oregon. Hazelnut trees prefer well-drained soil and full sunlight exposure. They can tolerate temperatures as low as -10 degrees Fahrenheit in winter, but they require a long, cool dormancy period followed by a warm growing season to produce nuts.
Best Way to Eat
Hazelnuts can be consumed raw or roasted, but roasting them often enhances their flavor and makes them easier to digest. They are commonly used in baking and cooking, adding a distinctive flavor to cakes, cookies, and many savory dishes. Hazelnuts are also the key ingredient in spreads like Nutella. To maximize their nutritional benefits, hazelnuts should be eaten with their skins on, as the skin contains a significant amount of fiber, flavonoids, and antioxidants. However, be aware that some people may find the skins slightly bitter. Hazelnuts are a good source of healthy fats, vitamins, and minerals, including vitamin E and B vitamins.
