I’ve been using it a lot the past five years for baking. Cookies, fish, frozen fries, pretty much any thing that goes in a baking pan and isn’t dripping wet. Carmel corn and sticky stuff that has to cool won’t stick to it either. We don’t use plastic wrap so on the rare occasion something goes in the microwave parchment paper will do for a temporary cover.
Makes cleanup a breeze. I found Reynolds makes it in 12” wide rolls too for less waste. Just don’t put it in an oven over 420 F.
