Stone Ground Teff Flour from Bob's Red Mill is a highly nutritious whole grain flour made from the smallest grain in the world. Compared to other grains, it has a much larger percentage of bran and germ, so it's a very good source of dietary fiber, protein and iron. Teff flour has long been a nourishing staple of highland Ethiopians. Now you too can enjoy its light, unique flavor and bountiful nutrition. Substitute up to 25% teff flour per cup of wheat flour in your favorite baked goods recipes for added nutrition and teff's unique and wholesome flavor.
