Which practice helps maintain the integrity of laminated dough during rolling?

• A. Keep butter cold, maintain separate layers.
• B. Roll quickly at high speed.
• C. Overwork the dough to tighten gluten.
• D. Warm dough to 90°F to relax the butter.

Answer: (A)

Maintaining the integrity of laminated dough during rolling hinges on keeping the fat cold and in separate layers between the dough sheets. Cold butter stays solid enough to form distinct sheets as you roll and fold, creating multiple, thin laminae that puff and crisp when baked. If the butter warms, it softens or melts and can ooze into the dough, causing the layers to fuse together instead of remaining distinct. That collapse of the laminated structure leads to a dense, less flaky crust and loss of the characteristic rise.

Keeping everything cold also helps with control during rolling, reducing tearing and ensuring even layers. In contrast, rolling quickly at high speed can generate heat that starts to melt the butter; overworking the dough develops gluten, making it tougher and less willing to laminate; warming the dough to relax the butter defeats the purpose by letting the fat break the separating layers.
