Bombe Nabab

Bombe Nabab (a praline-shelled frozen dessert with brandied candied fruit) teaches the architecture of a moulded frozen dessert: firm ice outside, a lighter center within, and clean contrast in every slice. The one true thing is temperature. If the shell softens while you fill it, those beautiful layers blur before the freezer can save them.

The original assumed a pâtissier could reach for pralined ice and an appareil à bombe already waiting, then clothe a large metal mould in a room built for cold work. At home, good praline ice cream supplies the outer ice, while five yolks make a small pâte à bombe, a yolk foam cooked with hot sugar syrup. Churning a separate ice and making brigade quantities are scaffolding, so they go. Chemiser, to clothe the mould evenly, is the dish and must stay. One cook, one stove, one evening of work, then the freezer keeps watch.

Dice the candied fruit smaller than a pea and scatter it between layers of filling. Stir it carelessly through a loose mixture and gravity gathers every jewel at the pointed end. Keep the praline shell hard as you fill it; that is the step that decides the Bombe Nabab.
