Puff Pastry (Pâte Feuilletée)

France — the technique is attributed to pastry chef Claude Lorrain (the painter) or more plausibly to François Pierre de La Varenne (1651 cookbook La Cuisinier François); the 17th-century codification of the turn-and-fold technique is specifically French; the technique spread through the classical French cooking tradition to dominate pastry making across Europe and the Americas

Classical puff pastry — a dough of flour, water, and salt wrapped around a block of pure butter, then folded and rolled repeatedly to create 729 alternating layers of dough and butter — is the most technically demanding pastry in the classical repertoire and the one whose result is most dependent on precision: temperature, rolling pressure, and resting. The layers (produced by six double-turns or four book-folds) create a laminated structure where each butter layer steams independently during baking, pushing the dough layers apart and producing the characteristic shatter-and-lift of puff pastry. The butter must remain plastic but cold — warm enough to deform without breaking the dough layers, cold enough not to melt and be absorbed. Rough puff pastry (where the butter is incorporated in chunks rather than as a block) is a practical approximation that produces 80% of the result with 50% of the effort.

The structural pastry of French cuisine — used in mille-feuille (Napoleon), beef Wellington shell, pithiviers, vol-au-vent, palmiers, and tarte Tatin; the pastry itself should be butter-forward and shatteringly crisp; it should produce visible, separate layers when cut; the sound of puff pastry breaking — a sharp crack — is the auditory confirmation of correct lamination
