Pantxineta

Pantxineta was created in 1915 at Casa Otaegui, the venerable San Sebastián patisserie founded in 1886 on Avenida de la Libertad. The name comes from the dessert's origin as an imitation of the French frangipane tart: an Otaegui baker filled it with thick custard instead of almond frangipane and capped it with puff pastry, originally calling it «frantxi-pan» (from «frangipane»), which the local Basque dialect soon contracted into «pantxineta». Casa Otaegui still makes the original and the recipe is essentially unchanged: the same all-butter puff, the same vanilla pastry cream, the same Marcona almonds. It's a Donostia (San Sebastián) merienda — afternoon snack — and the city's Día del Pantxineta in June celebrates it.

Casa Otaegui invented it in 1915 on San Sebastián's Avenida de la Libertad — same all-butter puff, cornstarch-stabilized vanilla cream, Marcona almonds. Eat it within 6 hours or the bottom goes soft.

A square the size of a deck of cards, height nearly equal to its base — almost vertical. The top is mahogany with bronzed almonds; one bite shatters the upper crust, releases a column of vanilla cream still slightly warm, then collapses through the lower crust which is firmer, almost biscuity. Sweetness is layered: pastry cream is mild, almonds toasted-bitter, icing sugar piercing. Eaten with espresso it's perfectly balanced; without coffee, the cream feels relentless. Best within 6 hours of baking — by tomorrow the bottom has gone soft.

The bake hinges on contrasting moisture management. The bottom puff is docked to keep it relatively flat — undocked, it would dome up into the cream and create a hollow. The top is left undocked so it rises tall and shatters dramatically. The pastry cream must be cornstarch-stabilized (not flour) — flour leaves a paste-like residue when baked, while cornstarch goes invisible. The 200°C oven is critical: lower and the cream weeps through; higher and the almonds blacken before the puff cooks.
