Buckwheat flour, also known as soba flour, is a gluten-free substitute for wheat flour that is becoming increasingly common in baking recipes. It has a nutty taste with a rich and robust flavor, making it perfect for pastries, pancakes, and bread. Buckwheat flour has a higher fiber content than most other flours and is rich in antioxidants, minerals, and vitamins. Some common synonyms for buckwheat flour include soba flour or kasha flour. Alternatively, buckwheat groats, which are the whole grain form of buckwheat, can be ground into flour, giving them another synonym - buckwheat groat flour. Whatever synonym you choose, this versatile flour is ideal for those with special dietary needs and provides enormous health benefits to your diet.
