CDM Dough Preparation & Ingredient Handling 3

Question 1

What is the recommended dough temperature range after mixing for optimal yeast-raised doughnut fermentation?

Accepted Answer

78–82°F (26–28°C)

Answer

A finished dough temperature of 78–82°F promotes consistent fermentation speed and proper gas production.

Question 2

Which flour property most directly affects water absorption in doughnut dough?

Accepted Answer

Starch damage level and protein content

Answer

Higher protein content and greater starch damage both increase a flour's capacity to absorb water during mixing.

Question 3

A baker notices the doughnut dough is sticky and difficult to handle after mixing. The most appropriate corrective action is to:

Accepted Answer

Incorporate small amounts of flour to achieve proper consistency

Answer

Adding flour in small increments adjusts hydration and improves dough handling without affecting leavening.

Question 4

What role does salt play in yeast-raised doughnut dough beyond flavor?

Accepted Answer

Salt strengthens gluten structure and controls yeast fermentation rate

Answer

Salt tightens the gluten network and regulates yeast activity, preventing over-fermentation.

Question 5

When using active dry yeast instead of instant dry yeast in a doughnut formula, the baker should:

Accepted Answer

Proof the active dry yeast in warm water (100–110°F) before adding to other ingredients

Answer

Active dry yeast requires rehydration in warm water to dissolve the protective coating and activate the cells before use.
