## Questions

**Which baking sheet doesn't warp?**

Nordic Ware Naturals Baker's Half Sheet has the best record (24 of 27), and Nordic Ware Naturals Quarter Sheet Pan has the highest share (12 of 13) from fewer shoppers.

**Why do baking sheets warp in the oven?**

Metal expands as it heats, and a thin pan or one that heats unevenly can twist or pop. Big temperature swings make it worse, like running cold water over a hot pan or heating an empty pan at high heat. Let pans cool before you wash them, and spread food across the whole sheet.

**Do Wilton cookie sheets warp?**

These two did for many shoppers. Wilton Ultra Bake Pro Cookie Sheet Set has the weakest record here at 2 of 28, and Wilton Mega Cookie Sheet stayed flat for 3 of 11. People are more likely to post a review when a pan warps, so low shares partly reflect who writes in.

**Will a warped baking sheet go back to flat?**

Sometimes. Many pans buckle with a pop in a hot oven and flatten again as they cool. If a pan stays bent once it's cool, it will rock on the rack and oil or juices can run to one side.
