Baking and Pastry Fundamentals Flashcards

In the creaming method, why are butter and sugar beaten together first?

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.

Which flour has the highest protein content?

Answer: Bread flour

Bread flour contains roughly 12-14% protein, giving it the strongest gluten potential.

A meringue refuses to whip to stiff peaks. What is the most common culprit?

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.

What is the purpose of an egg wash on pastry before baking?

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.

Why should you measure flour by weight rather than by volume cups?

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.

What happens if you bake bread without any salt?

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.

Which technique keeps blind-baked tart shells from shrinking down the pan sides?

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.
