What is the ingrediant in bread that makes it rise?

Yeast is a single-celled fungus that feeds on sugar and produces carbon dioxide and alcohol as byproducts. This carbon dioxide gas gets trapped in the dough, creating air pockets that cause the bread to rise.

Here's how it works:

1. Yeast is added to the dough.

2. Yeast feeds on the sugar in the dough.

3. Yeast produces carbon dioxide gas as a byproduct.

4. The gas gets trapped within the gluten structure of the dough.

5. The dough expands and rises.

While yeast is the primary ingredient for bread rising, there are other factors that influence the process, including:

* Temperature: Yeast thrives in warm temperatures, making it rise faster.

* Water: Water activates the yeast and helps it to function properly.

* Flour: Flour provides the gluten structure that traps the gas bubbles.

* Sugar: Sugar provides food for the yeast to ferment.

* Salt: Salt controls the rate of fermentation and adds flavor.
