Pistachio flour is a fine powder made from ground pistachios, a type of nut known for its rich flavor and vibrant green color. It is often used as a gluten-free alternative to traditional flours in baking and cooking. The flour retains the nutritional benefits of pistachios, including healthy fats, protein, and fiber. This versatile ingredient can enhance the taste and texture of various dishes, such as cookies, cakes, and pancakes. Additionally, pistachio flour can be used as a thickening agent in sauces or as a coating for meats and vegetables, adding a unique nutty flavor to meals.
