What does yeast do in cooking?

What Is Yeast in Baking? Yeast not only helps baked goods rise, but also it adds flavor.

How does yeast affect food?

Yeasts feed on sugars and starches, which are abundant in bread dough! They turn this food into energy and release carbon dioxide gas as a result. This process is known as fermentation. The carbon dioxide gas made during fermentation is what makes a slice of bread so soft and spongy.
