The Food Guys take a couple of shows to talk about einkorn , the ancient predecessor to modern wheat. Einkorn (rhymes with “fine corn”) means “one grain” in German. As with other ancient grains that have become trendy, the gluten structure of einkorn seems to suit some people better than that of modern bread wheat, Triticum aestivum . Einkorn boosters point out that, compared to bread wheat, it's low in starch and high in protein, and tastes nutty and earthy.
