To prevent collapse of pate a choux after baking, the product should be cooled how?

• A. Cool slowly after baking
• B. Cool rapidly in a draft
• C. Cool in the refrigerator immediately
• D. Cool while still in the oven

Answer: (A)

Pate a choux relies on steam to push and set its airy structure. After baking, the interior is still supported by that steam and by a delicate crust that needs time to firm up. Cooling slowly at room temperature allows moisture to escape gradually and gives the crust and the starch-protein network time to set without a sudden drop in temperature or rapid condensation of interior moisture. This gradual change helps keep the puff intact and prevents collapse.

Cooling in a draft, in the refrigerator, or while still in the oven causes the temperature to drop too quickly or moisture to condense too fast, which destabilizes the interior air pockets and the crust, making collapse more likely.
