Buckwheat Groats are the hulled seeds of the buckwheat plant and have a mild texture and grassy flavor compared to unhulled buckwheat, which retains its outer hull and has a stronger flavor and chewier texture. Because buckwheat is gluten-free, it is a great alternative to wheat flour.
I recommend that you use blond psyllium husk, as it won’t give any color to your gluten free bakes. Using other types of psyllium husk can sometimes result in your bread being darker in color (either brown or with a slightly purple-ish tinge).
