Unleavened refers to bread or other baked goods that are made without any leavening agents, such as yeast or baking powder. This means that the dough does not rise, resulting in a flat and dense texture. Unleavened bread is often used in various cultural and religious practices, including the Jewish holiday of Passover, where it symbolizes the haste of the Israelites' escape from Egypt. Common examples of unleavened bread include matzah, which is a traditional flatbread eaten during Passover, and tortillas, which are popular in many Latin American cuisines. Unleavened products are typically made from simple ingredients like flour and water, making them easy to prepare.
