acetate [as-i-teyt] noun
Flexible, clear plastic that comes in sheets and rolls. Acetate is used in commercial bakeries and by professional confectioners. It will impart a high sheen to tempered chocolate and can be used to create thin bands of chocolate to surround cakes, such as in the image below. It can also be formed into cylinders to mold desserts like layers of cake and mousses. Once set, the acetate can be removed and a layered dessert with very clean edges results.
Acetate can be used for home baking and candy making. Use in place of parchment when forming slabs of almond bark, for instance, or for placing dipped truffles upon. The bottoms will have a wonderful sheen.
