Which ingredient is NOT essential in yeast-leavened dough?

• A. Sugar
• B. Flour
• C. Water
• D. Salt

Answer: (A)

Yeast-leavened dough rises because yeast ferments sugars to produce carbon dioxide, which gets trapped in the gluten structure. The essential elements for this process are flour to provide gluten and structure, water to hydrate the flour and activate the gluten network (and to nourish the yeast), and salt to flavor and help regulate fermentation. Sugar is not required for the fermentation and rise; yeast can feed on sugars released from flour starches or on any added sugar, but many breads are made without any added sugar at all. Sugar mainly influences fermentation speed and browning, not the fundamental ability to leaven. Therefore, sugar is not essential.
