Cooking Lessons Baking and Pastry Fundamentals 3 — Questions and Answers
Question 1: In the creaming method, why are butter and sugar beaten together first?
- To incorporate air cells that help leaven the cake (Correct answer)
- To melt the sugar completely
- To activate the baking powder
- To cook the butter slightly
Correct answer: To incorporate air cells that help leaven the cake
Sugar crystals cut tiny air pockets into the butter, giving the cake lift and a fine crumb.
Question 2: Which flour has the highest protein content?
- Cake flour
- Pastry flour
- Bread flour (Correct answer)
- Self-rising flour
Correct answer: Bread flour
Bread flour contains roughly 12-14% protein, giving it the strongest gluten potential.
Question 3: A meringue refuses to whip to stiff peaks. What is the most common culprit?
- The sugar was added too slowly
- The eggs were too fresh
- The bowl was made of glass
- Fat contamination, such as a trace of egg yolk in the whites (Correct answer)
Correct answer: Fat contamination, such as a trace of egg yolk in the whites
Even a small amount of fat coats the egg white proteins and prevents them from forming a stable foam.
Question 4: What is the purpose of an egg wash on pastry before baking?
- It stops the pastry from rising
- It gives the crust a glossy, golden-brown finish (Correct answer)
- It keeps the interior raw
- It replaces the need for sugar
Correct answer: It gives the crust a glossy, golden-brown finish
Egg proteins and fats brown in the oven, creating shine and rich color on the crust.
Question 5: Why should you measure flour by weight rather than by volume cups?
- Weight is consistent, while a scooped cup can vary by 20% or more (Correct answer)
- Weight makes the flour easier to sift
- Volume measurements only work with metric recipes
- Scales remove the need for leavening
Correct answer: Weight is consistent, while a scooped cup can vary by 20% or more
Flour compacts unpredictably in cups, so weighing gives repeatable, accurate results.
Question 6: What happens if you bake bread without any salt?
- The bread will not brown at all
- The yeast cannot produce any gas
- The dough ferments too fast and the loaf tastes flat (Correct answer)
- The crust becomes too thick
Correct answer: The dough ferments too fast and the loaf tastes flat
Salt regulates yeast activity and enhances flavor, so its absence causes over-fermentation and blandness.
Question 7: Which technique keeps blind-baked tart shells from shrinking down the pan sides?
- Baking at the lowest possible temperature
- Chilling the shaped dough thoroughly before baking with weights (Correct answer)
- Adding extra water to the dough
- Rolling the dough as thin as paper
Correct answer: Chilling the shaped dough thoroughly before baking with weights
Chilling relaxes the gluten and firms the fat, so the shell holds its shape under pie weights.
