Chocolate Ice-cream Loaf

PREPARE THE TIN

Line a loaf tin with clingfilm.

MAKE THE BAILEYS ICE CREAM

For the Baileys ice cream, put 30 g sugar into a pan with the water and bring to the boil. Beat the egg yolks with the rest of the sugar until foamy, then slowly add the hot sugar water in a thin stream and continue beating until the mixture has cooled. Roughly chop the white chocolate couverture and melt over a hot bain-marie. Fold into the foamy egg yolk and sugar mixture with the Baileys. Whip the cream until stiff and fold into the mixture. Turn the mixture into the loaf tin and freeze for about 3 hours.

MAKE THE DARK CHOCOLATE ICE CREAM

Make the dark chocolate ice cream in exactly the same way, using the dark chocolate couverture and rum.

ASSEMBLE AND FINISH FREEZING

Turn the mixture onto the frozen Baileys ice cream and smooth the top. Freeze for about 2 hours then lay the sponge fingers on top and freeze for at least a further 2 hours.
