Dried yeast

Dried yeast is a dehydrated form of the yeast organism Saccharomyces cerevisiae, used as a leavening agent in baking bread, rolls, buns, and other yeasted goods. Unlike fresh yeast, it has a significantly longer shelf life and does not require refrigeration. It is most commonly sold in 7-gram packets, with one packet equivalent to approximately 25 g of fresh yeast. Active dried yeast should be dissolved in warm water with sugar before use, while instant yeast can be added directly to flour. Using the right amount ensures proper dough rising and an airy texture in the finished bake.
