When I use buckwheat flour in a recipe, I am using what I refer to as “raw” or “light” buckwheat flour. This is flour ground from the whole raw buckwheat kernel, but without the dark hull. What we commonly think of as buckwheat flour is grayish in color and has a fairly strong flavor, because the dark hull (or bran) is ground along with the kernel. It makes some pretty tasty pancakes, but I haven’t found it a pleasant addition or key ingredient to any other gluten-free recipes. When you purchase whole raw buckwheat and grind it into flour, you get a much lighter colored and flavored flour and this is great added to many recipes. You can grind it on your own in a mill or in a Vitamix.
