Greaseproof paper is a non-absorbent paper used especially in the United Kingdom and Australia for baking purposes. A protective barrier on the paper prevents grease from soaking through it.
How Greaseproof Paper is Made
Greaseproof paper is made from unbleached paper with a protective barrier added to repel grease. It generally is produced in sheets or rolls.
Greaseproof Paper vs. Parchment and Waxed Paper
Greaseproof paper is similar to parchment paper in texture, but where parchment paper has a non-stick surface, greaseproof paper does not. Parchment paper is preferable for lining bakeware when cooking something with a high sugar content. It is thinner than parchment and waxed paper, and transparent enough to be used as tracing paper. In the United States, where greaseproof paper is generally not commonly available, waxed paper can be used in its place.
Uses of Greaseproof Paper
Greaseproof paper is used for wrapping foods for storage, especially greasy foods such as butter, bacon or doughnuts. It is also used to separate layers of pancakes, cookies or other baked goods for storage. It can go from freezer to refrigerator to microwave with no problems. Greaseproof paper is also used to line cake and muffin tins, though, paradoxically, it must be lightly greased for these uses.
