Grains (Corn, Oats, Rye, Barley, and Ancient Grains)

Beyond wheat and rice, a dozen cereal species and several pseudo-cereals have shaped human diets across climates and cultures. Each has a distinct carbohydrate or protein chemistry that explains both its culinary limitations and its special strengths. Several (corn, rice, buckwheat, quinoa, amaranth, teff, millet) contain no gliadin — the protein implicated in celiac disease — making them safe for gluten-intolerant cooks.
