Tarte Bourdaloue

A Parisian creation of the second half of the 19th century, named after the rue Bourdaloue in the 9th arrondissement — a street itself named for the 17th-century Jesuit preacher Louis Bourdaloue. The exact creator is not firmly documented and accounts differ: the pâtissier-historian Pierre Lacam credits a cake called 'Bourdaloue' to Nicolas Bourgoin of the Lesserteur (Lesseur) house, set up in the early 1850s at 7 rue Bourdaloue, while other sources credit Fasquelle, who succeeded that house on the same street around 1860–70. Tellingly, the original was not a pear tart at all but a baked almond cake of ground almonds, sugar, eggs and starch finished with kirsch; the now-defining version — poached pears set in vanilla almond cream — is the form that later carried the name. It is best described as named for the rue Bourdaloue and traditionally credited to a pâtissier of that street (often given as Fasquelle, or Bourgoin before him), rather than tied to a single proven inventor or year.

A crisp, buttery sweet-pastry base gives way to a moist, dense layer of almond cream fragrant with vanilla and rum or kirsch. The poached pear is soft and melting, its flesh both grainy and juicy, sweet without being cloying. Toasted flaked almonds on top add a thin, nutty crunch against the soft interior. The almond and pear marry into something gentle and comforting, the flavours rounded rather than sharp, and it eats best warm or at room temperature.

The pears are poached, not used raw: simmered gently in a vanilla sugar syrup so heat softens the firm fruit, sugar penetrates the flesh, and the syrup keeps the cut surfaces from oxidising and browning. Poaching also drives off some raw juice so the fruit won't weep into the shell and turn the base soggy — too-wet pears are the classic failure here. They are arranged on almond cream spread in a pâte sucrée shell that is usually blind- or part-baked first to guarantee a crisp bottom. The filling is crème d'amande — ground almonds creamed with butter, sugar and egg — and becomes true frangipane when blended with a little crème pâtissière, classically about two parts almond cream to one part pastry cream, which adds moisture and a softer set. In the oven the egg coagulates and the butter melts and re-sets, so the cream puffs gently and bakes into a moist, dense, cake-like layer that cradles the pears; it should be set but still moist, never dry. Flaked almonds strewn on top toast in the same heat for colour and crunch.
