What could you use to replace yeast make dough rise?

* Baking soda and vinegar. This is a common leavening agent that is used in many recipes. It works by creating carbon dioxide gas when the baking soda and vinegar react with each other. This gas causes the dough to rise.

* Baking powder. Baking powder is a leavening agent that is made from baking soda, cream of tartar, and cornstarch. It works in a similar way to baking soda and vinegar, but it is more stable and does not require an acidic ingredient to activate it.

* Sourdough starter. Sourdough starter is a fermented dough that is made from flour and water. It contains live bacteria and yeast that produce carbon dioxide gas when they feed on the sugars in the flour. This gas causes the dough to rise.

* Commercial yeast. Commercial yeast is a type of yeast that is grown in a laboratory and then dried. It is used in many commercial baking applications.
