Now that is why my last attempt to bake Focaccia on butter paper (what wax paper is called around here) was such a disaster. I need to find if parchment paper is found in Indian stores.
The main difference between waxed paper and parchment paper is their respective coatings. Parchment paper is coated with silicone to give it a nonstick, heat-resistant surface, whereas waxed paper is coated with a wax such as soybean or paraffin.
Waxed paper is not meant for use in the oven—the wax coating on it will melt if the paper is exposed to direct heat.
