Which statement describes the effect of chilling dough on gluten and fat?

• A. It relaxes gluten and firms fat, helping dough roll-out and preventing shrinkage.
• B. It increases gluten development and makes dough tougher.
• C. It acts to ferment the dough to produce gas.
• D. It dries out the dough making it crumbly.

Answer: (A)

Chilling dough affects gluten and fat by slowing gluten development and firming the fat. When dough is cold, the fat solidifies and coats flour particles, which interrupts the formation of a strong gluten network. This relaxation of gluten means the dough won’t become overly elastic or tough, making it easier to roll out. The solid fat also shortens the gluten strands, acting as a barrier that helps prevent shrinkage during baking. This combination—less gluten development and firmer fat—produces a dough that’s easier to handle and yields a tender, flaky texture in pastry.

This isn’t about fermentation or gas production, which relates to yeast or chemical leaveners, and it doesn’t inherently dry the dough out.
