Which statement about the essential ingredients for yeast-leavened dough is true?

• A. The essential ingredients include Flour, Liquid, Yeast, and Salt
• B. Water is never used
• C. Sugar is essential in all dough
• D. Yeast is optional in some dough

Answer: (A)

Yeast-leavened dough relies on four baseline ingredients that provide structure and enable rise: flour, a liquid, yeast, and salt. Flour supplies gluten-forming proteins that form the stretchy network needed to trap gas. The liquid hydrates the flour and creates the environment for fermentation, feeding the yeast so it can produce carbon dioxide to lift the dough. Salt tightens the gluten just enough to improve strength and flavor while also moderating fermentation. The type of liquid can vary—water is common, but milk or other liquids can be used too. Sugar is not required; it can help feed the yeast and enhance browning, but dough can rise without added sugar. Yeast, of course, isn't optional in yeast-leavened dough—the leavening comes from the yeast's fermentation.
