Question: is parchment paper also wax paper?
Answer: Parchment paper -- which is available bleached and unbleached -- is coated with silicone, while wax paper is coated in, you guessed it, wax. Soybean or paraffin wax, to be precise. Their coatings give them different uses. Parchment paper's silicone coating makes it heat-resistant and nonstick.
