Bombe Alaska with Neapolitan ice-cream


  • Serves 12 people

When assembling the bombe, you need to make sure the ice-creams are soft enough to work with but not melted. You'll need to begin this recipe a day ahead.

  • 1 litre (4 cups) pouring cream
  • 2 vanilla beans, split and seeds scraped
  • 16 egg yolks
  • 400 gm caster sugar
  • 250 gm dark chocolate (70% cocoa solids), coarsely chopped
  • 375 gm raspberries (about 3 punnets)
  • Meringue
  • 4 eggwhites
  • 220 gm (1 cup) caster sugar
  • 2 tbsp cornflour, sifted
  • 2 tsp white vinegar
01   Combine half the cream, vanilla beans and vanilla seeds in a large saucepan, bring to the boil over medium-high heat. Meanwhile, whisk yolks and sugar in a large heatproof bowl until thick and pale (4-5 minutes). Pour cream mixture over yolk mixture, whisking continuously to combine, then return to a clean pan and stir continuously over low heat until mixture coats the back of a spoon thickly (10-15 minutes). Strain through a fine sieve into a bowl placed over ice, cool completely.
02   Whisk remaining cream until soft peaks form, fold through cooled custard. Divide into thirds, freeze one-third in an ice-cream machine according to manufacturer’s instructions and freeze until required.
03   Process raspberries in a food processor until smooth, then pass through a fine sieve to yield 250ml purée. Stir into one portion of the remaining custard, freeze in an ice-cream machine according to manufacturer’s instructions and freeze until required.
04   Melt chocolate in a heatproof bowl over simmering water, add to remaining custard, stir to combine. Freeze in an ice-cream machine according to manufacturer’s instructions. Meanwhile, remove vanilla and raspberry ice-creams from freezer to soften slightly.
05   Place a 2.5 litre tiffin mould (see note) in freezer until cold. Spoon large dollops of each ice-cream randomly into mould to create marbled pattern, tapping mould as you go to remove air bubbles. Smooth top, cover with plastic wrap and freeze for at least 8 hours.
06   For meringue, whisk eggwhites in electric mixer on high speed until stiff peaks form (1-2 minutes). Gradually add sugar, whisk continuously until stiff and shiny (4-5 minutes), add cornflour and vinegar, whisk to combine.
07   Dip mould in hot water and unmould onto a serving platter. Cover bombe with meringue using abstract stokes, ensuring there are no holes. Toast all over with a kitchen blowtorch set on medium until golden (1-2 minutes), cut into wedges, serve immediately.

Note Tiffin moulds are available from speciality cake shops such as Iced Affair.
