CDM Dough Preparation & Ingredient Handling 3 — Questions and Answers
Question 1: What is the recommended dough temperature range after mixing for optimal yeast-raised doughnut fermentation?
- 55–65°F (13–18°C)
- 78–82°F (26–28°C) (Correct answer)
- 90–95°F (32–35°C)
- 68–72°F (20–22°C)
Correct answer: 78–82°F (26–28°C)
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?
- Ash content
- Starch damage level and protein content (Correct answer)
- Granulation size of the flour particles
- Carotenoid pigment concentration
Correct answer: Starch damage level and protein content
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:
- Add more yeast to speed up fermentation
- Incorporate small amounts of flour to achieve proper consistency (Correct answer)
- Increase oven temperature to compensate
- Extend the mixing time without adding any ingredients
Correct answer: Incorporate small amounts of flour to achieve proper consistency
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?
- Salt activates yeast to begin fermentation faster
- Salt strengthens gluten structure and controls yeast fermentation rate (Correct answer)
- Salt provides a humectant effect to retain moisture in the finished doughnut
- Salt increases dough extensibility for easier sheeting
Correct answer: Salt strengthens gluten structure and controls yeast fermentation rate
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:
- Use 25% less active dry yeast by weight
- Proof the active dry yeast in warm water (100–110°F) before adding to other ingredients (Correct answer)
- Dissolve it in cold water to slow activation
- Add it directly with the dry ingredients without any change
Correct answer: Proof the active dry yeast in warm water (100–110°F) before adding to other ingredients
Active dry yeast requires rehydration in warm water to dissolve the protective coating and activate the cells before use.
Question 6: Which sugar provides the most consistent browning in doughnuts due to its invert sugar content?
- Granulated cane sugar
- Honey (Correct answer)
- High-fructose corn syrup
- Turbinado sugar
Correct answer: Honey
Honey contains invert sugar (glucose and fructose) that browns more readily than sucrose, producing deeper color at lower temperatures.
Question 7: During bench rest (intermediate proof) after dividing doughnut dough, gluten:
- Becomes stronger and more elastic
- Relaxes, making the dough easier to shape (Correct answer)
- Absorbs additional water from the environment
- Begins to break down, reducing dough strength
Correct answer: Relaxes, making the dough easier to shape
The rest period allows tightened gluten strands to relax, reducing dough springback during shaping and cutting.
