Is pizza bread unleavened or leavened?

Here's why:

* Leavening agents: Pizza dough typically uses yeast as a leavening agent. Yeast consumes sugar in the dough and releases carbon dioxide gas, creating bubbles that make the dough rise.

* Texture: The light and airy texture of pizza bread is a direct result of the leavening process.

* Taste: The fermentation process caused by yeast also contributes to the unique flavor of pizza bread.

While there are some variations, like thin crust pizzas that might use less yeast, most pizza doughs rely on leavening to achieve their characteristic texture and taste.
