Cooking Lessons Baking and Pastry Fundamentals 5

Question 1

Which stage of whipped egg whites is correct for folding into a soufflé base?

Accepted Answer

Medium-stiff peaks that are glossy but not dry

Answer

Glossy medium-stiff peaks hold air yet blend smoothly; dry, overwhipped whites break into clumps.

Question 2

What causes the hollow tunnels sometimes found inside muffins?

Accepted Answer

Overmixing the batter, which develops gluten and traps large gas channels

Answer

Overworked muffin batter forms gluten strands that channel gas into tunnels instead of an even crumb.

Question 3

Why is chocolate tempered before being used for dipped candies?

Accepted Answer

Tempering aligns cocoa butter crystals for snap, shine, and no gray bloom

Answer

Proper tempering forms stable beta crystals in the cocoa butter, giving a glossy finish and clean snap.

Question 4

In high-altitude baking, which adjustment is typically recommended?

Accepted Answer

Slightly reduce leavening and sugar while increasing liquid

Answer

Lower air pressure makes gases expand faster, so less leavening and more liquid prevent collapse and dryness.

Question 5

What is the difference between active dry yeast and instant yeast?

Accepted Answer

Instant yeast can be mixed directly into flour, while active dry is usually dissolved in warm water first

Answer

Instant yeast has finer granules that hydrate quickly in the dough, skipping the separate proofing step.
