BARM is a type of fermented dough used in baking. It is made from a combination of FROTH (5 letters), YEAST (5 letters) and LEAVEN (6 letters). FROTH is a foam created by whisking or shaking a liquid, while YEAST is a single-celled organism that helps to create carbon dioxide and alcohol during fermentation. LEAVEN is a substance, such as YEAST, that is added to dough to make it rise. Together, these three ingredients create the BARM dough, which is used to make breads, cakes, and other baked goods.
