Puff pastry is a light, flaky type of pastry that expands or "puffs" up during baking due to the high water content in its buttery layers. The pastry is made by intricately folding dough and butter together, creating multiple thin layers. When baked, the water in the butter turns into steam, causing the individual layers to rise and create its signature airy texture. Puff pastry is versatile and it can be used in both sweet and savory recipes. It is commonly used in dishes such as turnovers, tarts, and pot pies. Despite the labor-intensive process, the result is a beautifully golden, crisp and delicate pastry that provides a sophisticated touch to any dish.

Puff Pastry can typically be found in the frozen foods section of a grocery store. Look for it near other frozen breads and doughs.
