Yeast-free puff pastry consists of wheat flour, water, butter (margarine) and salt. Contains vitamins from groups B, A, E, H, PP, as well as organic acids, potassium, calcium, sodium, iron, phosphorus, chlorine, etc. The finished dough is sold in frozen layers. It must be thawed at room temperature before use. Home cooking is quite difficult. You need to knead the dough from flour, water and salt and then roll out the butter in thin layers. The more layers, the better the dough. Before baking, the dough is rolled out in different directions in thin layers. Puff pastry is used for baking mainly crispy products - puffs, tongues, pies, pastries, croissants, millefeuilles, samsa and, of course, Napoleon cake.
