Question 1

A crème anglaise curdles during preparation. What temperature threshold was most likely exceeded?

Accepted Answer

185°F (85°C), where egg yolk proteins over-coagulate

Answer

Crème anglaise must stay below about 185°F because yolk proteins curdle beyond that point.

Question 2

Why is a baker's percentage system preferred in professional bread formulas?

Accepted Answer

All ingredients are expressed relative to flour weight, making scaling consistent

Answer

Baker's percentage states each ingredient as a percent of total flour weight, allowing accurate scaling of any batch size.

Question 3

Which sugar cooking stage is required when preparing Italian meringue?

Accepted Answer

Soft ball stage, about 240°F (115°C)

Answer

Italian meringue is made by streaming soft-ball-stage syrup (approximately 240°F) into whipping egg whites.

Question 4

A batch of muffins comes out with tough texture and elongated interior tunnels. What error in the muffin method most likely occurred?

Accepted Answer

The batter was overmixed after the liquid was added to the dry ingredients

Answer

Overmixing develops gluten in muffin batter, creating toughness and tunnels in the baked product.

Question 5

What distinguishes puff pastry from croissant dough in composition?
