This video provides a detailed explanation of how to make a perfectly crispy pie bar with many layers. First, mix all-purpose flour, salt, sugar, and water to make the dough, then add room-temperature unsalted butter and knead, then let it rest in the refrigerator. Next, roll out the butter thinly, wrap it in the dough, and roll it out with a rolling pin and fold it several times to create beautiful layers. The key is to work quickly so that the butter does not melt. Finally, cut the dough, bake it in the oven, and decorate it with melted white chocolate to finish. This authentic pie that you can make at home is perfect for a home café or as a gift.
