Does Pillsbury refrigerated biscuits contain yeast?

Pillsbury refrigerated biscuits do not contain yeast. They are made with baking powder, which is a chemical leavening agent that creates bubbles in the dough and causes it to rise.

You can tell they don't contain yeast because:

* They rise quickly: Yeast takes time to ferment and rise. Biscuits made with baking powder rise much faster.

* They don't have a yeasty flavor: Yeast imparts a distinctive flavor to bread. Biscuits made with baking powder have a different, more neutral flavor.

If you're looking for biscuits with a more traditional yeast flavor, you'll need to look for a recipe that uses active dry yeast.
