What Is Active Yeast?
A living microorganism, a single-celled fungus, sold in granular form, that ferments sugars in dough to produce carbon dioxide, causing bread to rise.
"Unlike instant yeast, active dry yeast requires "proofing" in warm liquid to ensure it's alive and ready to work, a crucial step for successful bread baking."
