Made from paper pulp treated with sulphuric acid and coated with silicon.

Parchment paper is paper that has been soaked in sulfuric acid, but there are now also environmentally friendly parchment papers made from only recycled and biodegradable paper. A Silpat or silicone baking mat are other alternatives.

Parchment paper can be used to cook fish en papillote, cookies, pastries, and tarts.
