Pastry sheets are ready to bake pastry bases which can be prepared into puff pastry. Whether you're a beginner or an experienced cook, using Puff Pastry Sheets makes pastry baking an easy task. Puff Pastry is a deliciously light, flaky pastry made from dozens of layers of specially prepared pastry dough. This painstaking process yields a pastry made of dozens of layers. The pastry "puffs" when baked causing the layers to separate. The Puff Pastry sheet is ready to bake, so you can skip the work and still enjoy perfectly made golden, flaky pastry. You would need to remove as many pastry sheets as needed (wrap unused sheets in plastic wrap or foil and return them to the freezer). Thaw the sheets at room temperature about 30 minutes to an hour. Work with one pastry sheet at a time, keeping the others in the refrigerator. Unfold pastry sheets on a lightly floured board, countertop or pastry cloth. Seal filled pastries by brushing a mixture of beaten eggs and water between layers, then pinching or pressing them together. For thin, crisp pastries, roll sheets to a 1/4-inch thickness. Bake prepared sheets in a preheated conventional oven (not a microwave) and the flaky or puffy pastries can be enjoyed.
