Walnut flour is a finely ground powder made from whole walnuts. It boasts a rich, nutty flavor and aroma, making it a delicious and gluten-free alternative to wheat flour in baking. Its texture is slightly coarse compared to all-purpose flour, lending a pleasant crumbly quality to baked goods. Walnut flour appears as a light to medium brown powder, depending on the roasting level of the walnuts before grinding. It's a great ingredient for people looking for gluten-free flour, or a protein-rich flour with a distinctive, pleasant flavor.

Walnut flour is high in oil, so it's best stored in an airtight container in the refrigerator or freezer to prevent it from going rancid. Refrigeration can extend its shelf life for a few months, while freezing can keep it fresh for up to a year. Ensure the container is tightly sealed to avoid moisture absorption and maintain its flavor. Bring to room temperature before using for best results in baking.
