Nut flours are finely ground powders made from various types of nuts, such as almonds, hazelnuts, or cashews. They are often used as gluten-free alternatives to traditional wheat flour in baking and cooking. Nut flours add unique flavors and nutritional benefits, including healthy fats, protein, and vitamins. These flours can be used in a variety of recipes, including pancakes, cookies, and bread. When substituting nut flour for regular flour, it's important to adjust the liquid content, as nut flours can absorb more moisture. They are popular in paleo and keto diets for their low carbohydrate content.
