Bombe Sultane

Bombe Sultane (chocolate ice with a praline frozen-mousse centre) teaches the architecture of a classical frozen dessert: a firm shell around a lighter heart. The one true thing to know before touching a pan is this: the pounded Pralin goes in last, only after the cream has been folded through. Stir it early and its weight knocks the air from the centre.

The original entry gives architecture rather than quantities because the grand kitchen already had chocolate ice, Pralin, and Bombe-preparation waiting in separate departments, with a glacier tending moulds in tubs of salted ice. Here both frozen mixtures are made in small batches sized for one 1-litre mould. A domestic ice-cream machine and freezer replace the freezing chest, while a chilled stainless-steel bowl replaces the dedicated bombe mould. Those extra hands and tubs were scaffolding. The chocolate lining, the pâte à bombe, a whipped yolk-and-hot-syrup base, and the final fold of Pralin are the dish and must stay.

One cook, one stove, one evening. The freezer does the waiting. Fold the Pralin only when the cream is completely incorporated, then stop as soon as its amber flecks run through the mousse.
