This is a type of yeast used in baking. It is a leavening agent, meaning it helps dough rise. This particular yeast is active dry, which means the yeast cells are dormant until activated by liquid. It is also noted as being without ascorbic acid, which is sometimes added to yeast products.
Active dry yeast is a staple for anyone who bakes bread or other yeasted doughs.
To use active dry yeast, you typically need to 'proof' it first. This involves dissolving the yeast in warm liquid, usually water or milk, along with a pinch of sugar. Let it sit for about 5 to 10 minutes until it becomes foamy. This indicates the yeast is alive and ready to work. Once proofed, you can add it to your other dough ingredients. The yeast will then consume sugars and produce carbon dioxide gas, which causes the dough to expand and become light and airy during baking.
Compared to instant yeast, active dry yeast requires a separate proofing step before mixing into the dough. Instant yeast can often be mixed directly with dry ingredients. This version is also made without ascorbic acid, which some bakers prefer for specific recipes or flavor profiles.
Home bakers and professional bakers use this yeast for its reliable leavening power.
Once opened, store the remaining yeast in an airtight container in a cool, dry place, such as the refrigerator or freezer. This helps maintain its activity and extends its shelf life. Always check the expiration date before use.
