Parchment paper and wax paper both serve as a nonstick paper that can be used to line baking sheets, but they are not interchangeable. Parchment paper is treated with silicone, making it nonstick and heat resistant up to 420°F. Wax paper is coated with a wax such as soybean or paraffin which makes it moisture-resistant and suitable for wrapping food. Parchment paper can be used for baking, roasting, and reheating foods in the oven, while wax paper is not suitable for oven use. Parchment paper can also be used to prevent sticking when rolling out dough or as a nonstick surface when making candy. Wax paper is an ideal choice for lining countertops when making sticky or gooey recipes because the wax coating prevents the food from sticking.
