The term pre-ferment refers to a process of preparing a dough or batter for baking, which involves fermenting the mixture with yeast or other microorganisms. The antonyms for pre-ferment are non-fermented, non-risen, unfermented, and unleavened. Non-fermented implies the absence of any fermentation process in the dough or batter, while non-risen implies that the dough or batter did not rise due to the absence of yeast. Unfermented mostly refers to drinks like beer, which have not undergone the fermentation process. Finally, unleavened means that the dough or batter has not been mixed with any leavening agent, such as yeast or baking powder, and will not rise.
