Praline

The much-repeated origin credits the praline to the household of César, duc de Choiseul, comte du Plessis-Praslin (1598–1675): in 1636 his officier de bouche — usually named as Clément Jaluzot, though some accounts give the cook's name differently — is said to have caramelised roasted almonds in sugar, and the sweet later took the count's name. He went on to sell the 'praslines' in Montargis, south of Paris, where the shop traded under the sign 'Au Duc de Praslin'. The documented anchor is the Montargis confiserie itself: in 1903 Léon Mazet bought the recipe and established Maison de la Prasline Mazet, which still makes the praslines of Montargis to a recipe transmitted orally until Mazet wrote it down around 1920. The duke-and-cook story is best treated as a famous attribution rather than established fact; the name later gave French 'praliné' (the ground paste) and 'pralin'.

First the hard caramel crust cracks under the teeth — a brittle, glassy shatter — giving way to the dense crunch of the toasted almond inside. The flavour is deeply sweet and frankly caramelised, edged with the roasted, faintly bitter note of the nut and a whisper of its oil. The crust is rough and matte where the sugar sanded, not the smooth glaze of a dragée.

The crust is built by deliberately crystallising sugar — the technique called sablage. Nuts are heated in a sugar syrup that is stirred as it concentrates; at the right point the sucrose seizes and recrystallises around each nut, turning dry, white and sandy ('sablé', like sand). Continued heat then partly re-melts that sanded coating into caramel, so the finished crust is a crystalline-caramel shell rather than a clear glaze — rough, opaque and crunchy. Stirring is the whole game: agitation seeds the crystals that give the sandy texture, where leaving the syrup still would instead carry it smoothly up to a clear caramel. The almonds are usually pre-roasted, which develops their flavour and drives off moisture so the crust adheres and stays crisp.
