Puff pastry (French: pâte feuilletée) is a laminated dough made by enclosing butter in a détrempe (base dough) and repeatedly folding and rolling it to create alternating layers of dough and fat. During baking, water in the dough and butter turns to steam, lifting and separating the layers to produce a crisp, flaky structure.
The dough is rolled and folded through a series of turns, with resting and chilling between stages to relax gluten and keep the butter firm and plastic. A single turn folds the dough into thirds; a double turn folds it into quarters. The number and sequence of turns depend on the recipe and desired result. Butter should remain evenly distributed rather than melting into the dough or breaking into hard pieces.
Work at a cool temperature, use light and even rolling pressure, keep the edges neat and brush away excess flour before folding. If the dough becomes too warm or elastic, rest it under refrigeration before continuing. When cutting shapes, use a sharp knife and avoid crushing the laminated edges, which can restrict lift.
Puff pastry is used for mille-feuille, vol-au-vent, palmiers, savoury tarts, turnovers and en croûte preparations. It can be made by traditional French methods or purchased ready-made for production kitchens.
Chef’s tip: Bake in a properly preheated oven and allow sufficient time for the pastry to cook through. A deeply coloured exterior with a dry, crisp interior is preferable to pale pastry that remains doughy between the layers.
Key distinction: Puff pastry is laminated but is not normally yeast-leavened. Croissant dough is also laminated, but it contains yeast and is enriched.
