Puff pastries are a type of light, flaky pastry made from layers of dough and butter. The dough is rolled and folded multiple times to create thin layers, which puff up when baked due to steam. This unique texture makes puff pastries ideal for both sweet and savory dishes. Common uses for puff pastries include croissants, tarts, and vol-au-vents. They can be filled with a variety of ingredients, such as fruits, creams, or meats, making them versatile for different cuisines. Puff pastries are often enjoyed as appetizers, desserts, or even main courses.
