CCC Baking and Pastry Operations 2

Question 1

A chef notices their choux paste puffs collapse after being removed from the oven. What is the most likely cause?

Accepted Answer

The pastries were underbaked, leaving too much internal moisture

Answer

Underbaked choux retains steam and moisture inside, causing the structure to collapse as it cools.

Question 2

Which flour is most appropriate for producing a tender, fine-crumbed genoise sponge?

Accepted Answer

Cake flour with approximately 7-9% protein

Answer

Low-protein cake flour minimizes gluten development, yielding the delicate crumb desired in genoise.

Question 3

During lamination of croissant dough, the butter block breaks into shards instead of rolling out evenly. What condition most likely caused this?

Accepted Answer

The butter was too cold and brittle relative to the dough

Answer

Butter that is too cold shatters during rolling instead of spreading in continuous layers with the dough.

Question 4

What is the primary function of adding an acid such as cream of tartar when whipping egg whites for meringue?

Accepted Answer

It stabilizes the foam by slowing protein coagulation

Answer

Acid lowers the pH, which stabilizes the egg white proteins and produces a more resilient foam.

Question 5

A pastry cook must temper dark chocolate for dipped confections. To which working temperature range should the chocolate be brought after seeding?

Accepted Answer

Approximately 88-90°F (31-32°C)

Answer

Properly tempered dark chocolate is worked at about 88-90°F to maintain stable Form V cocoa butter crystals.
