Overview: Follow along as Claire makes a delicious puff pastry recipe from scratch. This recipe, a hybrid of pie dough and traditional puff pastry, relies on a series of rapid folds to flatten slices of butter into thin sheets within the dough, which then release steam during baking and produce a flaky, layered effect. The key to the flakiest pastry is to keep it very cold, so feel free to return the dough to the refrigerator as frequently as needed while you work.
