What is used to make bread which rhymes with low?

The answer is "dough". Dough is a mixture of flour, water, yeast, and salt that is used to make bread, pizza, and other baked goods. It is a viscous, elastic substance that can be shaped into various forms. When dough is baked, the yeast ferments the sugars in the flour, producing carbon dioxide gas that causes the dough to rise. The final product is a light and fluffy loaf of bread.
