Question 1

What is the primary function of eggs in a chiffon cake batter?

Question 2

Which type of flour produces the most tender pie crust?

Accepted Answer

Pastry flour

Pastry flour has a lower protein content (8–9%) than all-purpose, resulting in less gluten development and a more tender crust.

Question 4

At what internal temperature is a properly baked custard considered set?

Accepted Answer

170°F (77°C)
