Question: what is the difference between wax paper and par?
Answer: Parchment paper is coated with silicone to give it a nonstick, heat-resistant surface, and wax paper (or waxed paper) is—as the name suggests—coated with a soybean or paraffin wax. Because of this coating, wax paper is not meant for use in the oven—the wax coating on it will melt if the paper is exposed to direct heat.
