What role does yeast play in Danish Dough?

• A. It sweetens the dough
• B. It aids in leavening
• C. It prevents dough from becoming tough
• D. It adds color during baking

Answer: (B)

Yeast plays a crucial role in Danish dough primarily due to its ability to aid in leavening. When yeast is introduced to the dough, it ferments the sugars present and produces carbon dioxide gas as a byproduct. This gas gets trapped within the layers of the dough, causing it to rise and expand. The leavening process not only contributes to the light and airy texture that is characteristic of Danish pastries but also helps to develop the flavor through fermentation.

The other choices do not accurately represent the function of yeast in Danish dough. While sweetness, toughness, and color during baking are important characteristics in baking, they are not directly the result of yeast's action in this specific context. The sweet flavor profile of Danish dough is generally achieved through the addition of sugar, while the prevention of toughness is typically addressed through the proper mixing and handling techniques of the dough. Color development during baking is mainly due to the Maillard reaction and caramelization rather than yeast activity.
