Parchment Paper Tip
Do you wonder how to make a piece of parchment paper lie flat on the baking sheet? Well, wonder no more!
Parchment paper is often sold in rolls, so when you want to use it, it remains in a curl. When you buy a roll, take a few minutes to cut it into lengths to fit your baking sheets. Put the stack of cut sheets between two baking sheets, then store them together to “iron” the parchment flat. If you have to use curly paper, butter the pan first to help the paper adhere.
