An old-school French pâtisserie cake: an oval choux bun filled with kirsch-scented pastry cream and capped on top with a hard sheet of caramel, sometimes finished with a few colored sugar strands or chopped pistachio. A cousin of the éclair and the religieuse from the choux family, it belongs to the classic glass-case repertoire of the neighborhood pâtisserie. Crisp shell, boozy cream, and a brittle caramel lid make up its three-part appeal.
A traditional French pâtisserie item of the choux family whose name is commonly linked to Gustave Flaubert's 1862 novel 'Salammbô', a connection that is often repeated but not firmly documented. It sits among the classic neighborhood-bakery choux cakes — alongside the éclair, the religieuse, and the salammbô's near-twin — that were codified in French pastry through the later nineteenth and twentieth centuries. Once a fixture of every pâtisserie counter, it is now seen as an old-fashioned cake kept alive by traditional shops.
Bite through the brittle caramel cap, which cracks like glass, into a thin crisp choux shell, then a flood of cool pastry cream sharp with kirsch. The contrast is the whole dish: hard sweet caramel, hollow crackling pastry, soft fragrant cream underneath. The kirsch gives it a grown-up, faintly cherry-almond warmth that sets it apart from a plain cream puff. Eaten fresh, the shell is crisp; left to sit, the cream softens it and the caramel begins to weep.
Choux paste is cooked twice — flour gelatinized in boiling butter-water on the stove, then eggs beaten in — so that oven steam blows the dough into a hollow shell that bakes crisp and dry. The filling is a kirsch-flavored crème pâtissière thickened by cooking starch and egg, and the lid is sugar caramelized to the hard-crack stage and set as a thin sheet. Timing matters: the caramel must be applied while fluid and used quickly, and the buns filled close to serving so the shell does not go soft.
Variations
Colored sugar strands, chopped pistachio, or a dab of fondant sometimes decorate the caramel top. Some shops flavor the cream with rum or vanilla instead of kirsch, and the very similar salammbô is essentially the same cake under the fuller spelling. The choux base ties it to the éclair (filled and iced) and the religieuse (stacked choux), all worked from the same paste in the classic pâtisserie.

Cook choux paste by boiling water, butter, and salt, beating in flour, then beating in eggs off the heat.
- 225 min
Pipe oval buns onto a lined tray and bake until puffed, golden, and dry inside.
Watch outPipe the buns and bake until they're puffed, golden and dry right through — a damp interior collapses once it cools and won't hold the filling.

Cook a pastry cream from milk, sugar, egg yolks, and starch, then cool it and beat in kirsch.
- 48 min
Pierce each cooled bun and pipe the kirsch pastry cream inside until full.

Cook sugar to a deep amber hard-crack caramel.
Watch outCook the caramel to a deep amber hard-crack and use it fast while fluid — let it thicken and you can't dip a clean glassy cap.
- 65 min
Dip the top of each filled bun into the hot caramel to set a glassy cap.
Watch outDip the tops close to serving — the caramel cap softens and weeps if the filled buns sit too long.

Decorate with colored sugar or pistachio while the caramel is still tacky and serve fresh.
