👉 "Leavenless" is a concept in culinary science that refers to grains or other ingredients that are not easily leavened. These types of grains and other ingredients are typically used to make bread, pancakes, and other baked goods, as they do not require the use of yeast or other leavening agents. Leavenless grains include wheat, rye, barley, oats, rice, and amaranth.
