Galette des Rois (Puff Pastry Almond Frangipane Pie)

Puff pastry is built from hundreds of alternating layers of dough and butter that have been folded and rolled repeatedly. In the oven, the moisture inside the butter converts to steam and forces the layers apart, causing the dough to expand dramatically and set into a structure of thin, translucent sheets stacked one on top of the other. When the baked galette is cut, those layers are visible in cross-section, and the pastry shatters into golden flakes with any pressure - the defining textural characteristic of well-made puff pastry. The frangipane filling is made from butter, eggs, sugar, and ground almonds whisked together into a smooth cream. It bakes into something dense and moist, with the almond flavor concentrated and deepened by the heat in a way that raw almond paste cannot replicate. Before baking, a small porcelain figurine called a feve is pressed into the frangipane and sealed inside. Whoever receives the slice containing the feve is crowned king or queen for the day with a paper crown that typically comes with the galette from the bakery. The top of the pastry is scored with a sharp knife in decorative patterns of leaves, spirals, or geometric designs, and brushed with an egg wash that caramelizes in the oven to produce a lacquered golden surface with the scored lines standing out in relief. In France, bakeries sell galette des rois throughout January, and sharing one with family or colleagues is a significant social ritual at the start of the new year.
