Why Does Bread Rise?

💡 Simple Explanation

The secret is tiny living things called yeast! When you add yeast to dough, it starts eating the sugars in the flour. As it eats, it burps out a gas called carbon dioxide - the same gas in soda bubbles! These tiny bubbles get trapped in the stretchy dough and puff it up like little balloons. When you bake the bread, the heat makes the bubbles expand even more, and then the bread gets firm around them. That's why bread has all those holes inside!
