You probably mean “parchment paper”.
It’s a special kitchen paper used mostly in baking and cooking.
What it is
parchment paper baking is a grease-resistant, non-stick paper that is usually coated with silicone, making it safe for oven use. It helps food not stick to trays and makes cleanup much easier. (Baking Bites)
What it’s used for
- Baking cookies, cakes, brownies
- Lining baking trays and cake pans
- Roasting vegetables or chicken
- Preventing food from sticking without extra oil
- Easy cleanup after cooking (Reynolds Brands)
Important note
Don’t confuse it with wax paper — wax paper is not safe for ovens and can burn.
If you want, tell me what you’re trying to cook, and I can suggest whether you actually need parchment paper or a substitute.
