Buckwheat flour is made from grinding the seeds of the buckwheat plant, specifically the buckwheat groats. Buckwheat flour is naturally gluten-free, making it a popular choice for those following a gluten-free diet. It is commonly used in baking recipes to make bread, pancakes, muffins, cookies, and other baked goods. Buckwheat flour is also used in non-baked recipes, such as noodles and pasta. In Japanese cuisine, buckwheat flour is specifically used to make soba noodles.
