Buckwheat Flour has a rich, nutty flavor and has very high nutritional value. It's high in fiber, amino acids, protein, niacin and vitamin B. Although used as a cereal grain, it is technically an herb. We use buckwheat flour as a substitute often in recipes that call for wheat flour. Buckwheat is also gluten free. Bouchard Family Farm has a site with recipes and additional information about buckwheat.
