CDM CDM Glazes, Fillings & Toppings 2 — Questions and Answers
Question 1: What is the purpose of adding shortening or oil to a glaze recipe?
- To improve sheen and slow crystallization (Correct answer)
- To add sweetness
- To thicken the glaze
- To increase shelf life of the doughnut
Correct answer: To improve sheen and slow crystallization
Fat in a glaze improves its sheen and inhibits sugar crystallization, resulting in a smoother, longer-lasting finish.
Question 2: When injecting a cream filling into a doughnut, which tool is most commonly used?
- A pastry bag with a bismarck tip (Correct answer)
- A ladle
- A piping bag with a star tip
- A squeeze bottle with a wide nozzle
Correct answer: A pastry bag with a bismarck tip
A bismarck (or filling) tip is a long, narrow nozzle that inserts into the doughnut side to deposit filling without tearing the exterior.
Question 3: Why should fruit jam fillings for doughnuts have a higher sugar content or be specially formulated?
- To prevent soaking into the dough and to maintain food safety (Correct answer)
- To make the filling sweeter
- To reduce overall cost
- To allow faster injection
Correct answer: To prevent soaking into the dough and to maintain food safety
Higher sugar content lowers water activity, preventing the filling from making the dough soggy and inhibiting microbial growth.
Question 4: What is the role of gelatin when added to a whipped cream doughnut filling?
- To stabilize the whipped cream so it holds its shape (Correct answer)
- To add sweetness to the filling
- To prevent oxidation of the cream
- To reduce calories in the filling
Correct answer: To stabilize the whipped cream so it holds its shape
Gelatin acts as a stabilizer, preventing the whipped cream from deflating or weeping during storage and display.
Question 5: Which type of sprinkle is most resistant to color bleeding when placed on a wet glaze?
- Nonpareils with a sugar shell coating (Correct answer)
- Jimmies (rod sprinkles)
- Sanding sugar
- Colored coconut flakes
Correct answer: Nonpareils with a sugar shell coating
Nonpareils have a hard sugar shell that resists dissolving quickly, making them more resistant to color bleeding on wet glazes.
Question 6: What is the correct method for applying a maple glaze to achieve full, even coverage?
- Dip the top of the doughnut face-down into the glaze and let excess drip off (Correct answer)
- Brush glaze on with a pastry brush
- Pour glaze over a rack of doughnuts
- Spray glaze using an atomizer
Correct answer: Dip the top of the doughnut face-down into the glaze and let excess drip off
The dip-and-drip method allows the glaze to coat the crown of the doughnut evenly and lets gravity remove excess for a clean finish.
