Red Star Active Dry Yeast is a traditional, all-natural leavening agent used for developing flavor and providing a steady rise in all types of yeast doughs, from low-sugar to enriched, suitable for breads, rolls, pizza, and pastries, featuring a longer shelf life than cake yeast when kept dry, and known for its reliable performance in both traditional and bread machine methods. It contains just yeast (and sometimes Sorbitan Monostearate) and is gluten-free, non-GMO, and kosher.
