Nut-based flours are made by grinding nuts into a fine powder, creating a gluten-free alternative to traditional wheat flour. Common types include almond flour, hazelnut flour, and cashew flour. These flours are rich in healthy fats, protein, and essential nutrients, making them a popular choice for those following paleo or keto diets. In baking, nut-based flours can add moisture and a unique flavor to recipes. They are often used in cookies, cakes, and bread, but may require adjustments in liquid and leavening agents due to their different properties compared to wheat flour. Nut-based flours can also be a great option for those with gluten sensitivities.
