Orejas

The oreja is the Mexican name for the palmier, the French sugared puff-pastry cookie that entered the country's bakeries along with the wider tradition of pan dulce. Mexico's pan dulce grew out of French and broader European baking that took hold across the nineteenth century — French bakers and tastes were especially influential during the brief empire of Maximilian I (1864–67) and the long Francophile rule of Porfirio Díaz — and the palmier was naturalized as one more shape in the panadero's repertoire. As a folk bakery item it carries no fixed inventor or origin date; it is simply one of the standard pieces a Mexican bakery turns out daily. The Spanish name nods to the curl of the pastry, the same way the French palmier names it for a palm leaf.

An oreja is all shatter — bite in and it breaks into thin, brittle leaves that crumble and scatter, with none of the chew of bread. The caramelized sugar gives a deep, almost toffee sweetness and a faint pleasant bitterness at the edges where it has browned hardest, while the buttery pastry underneath is rich and flaky. The surface is glassy and glossy, the inside dry and crisp all the way through. It is light and fragile, a pastry that fragments at the first bite and dusts your fingers with caramel flakes.

The oreja rides on lamination. Puff pastry is built by folding a slab of butter into dough and rolling and folding it again and again, so the finished dough holds dozens to hundreds of paper-thin alternating sheets of dough and fat. In the oven the water in the butter and dough flashes to steam and the trapped fat melts, prying each layer apart and lifting the pastry into crisp leaves — a purely mechanical, ungreased rise with no yeast or chemical leavener. The Mexican twist is to roll and fold the dough in granulated sugar instead of flour: as it bakes, that sugar melts and caramelizes against the hot pan, browning through caramelization to deep amber and setting hard as it cools, so the pastry crisps and lacquers at once. The sheet is rolled inward from both ends to meet in the middle, chilled firm, then sliced crosswise — each slice opening in the heat into the double-lobed "ear." Keeping butter and dough cold through every fold is what preserves the distinct layers; if the butter warms and merges into the dough, the pastry bakes dense instead of flaky.
