What does leavening mean?
Leavening is a substance, process, or influence that makes something rise or become more animated. In baking, the word refers to an agent such as yeast, baking powder, or baking soda that produces gas and causes dough or batter to expand. Yeast acts by fermenting sugars and releasing carbon dioxide, which forms the bubbles that give bread its texture. The word can also describe the process of raising dough, though it is more common when naming the agent. Figuratively, leavening is an enlivening influence: a speaker may provide leavening to a solemn gathering through wit, energy, or unexpected humour. Although everyday bakers often simply say yeast, leavening is useful in technical, culinary, and figurative writing because it distinguishes the cause of rising from the other ingredients and can also evoke the transformative effect of a lively presence or idea.
