1 plain sponge cake (homemade or bought) 2 tablespoons Marsala (or your favourite liqueur) 2 tubs gourmet ice cream (use different flavors) 3 egg whites (keep half of an empty eggshell for use later) 1/3 cup caster sugar 3 tablespoons brandy to ignite
The frozen part of this dessert can be prepared ahead of time, leaving only the meringue layer to be completed before serving. Allow about 10 minutes to organize the sponge base and ice-cream layers prior to freezing. Before serving your dessert, allow around 10-15 minutes to complete the meringue, create the final look of your bombe Alaska and cook.
Place the sponge cake onto a plate. Cut the sponge into a round shape by using the lid of the ice-cream tub as a template, brush away the crumbs and drizzle Marsala over the cake disc. This will form the base of the bombe Alaska.
Most people would just use one tub of ice-cream but Geoff uses two flavors to create a superb effect. Dip the ice-cream tubs into warm water for about 10 seconds then turn them out onto a plate. Both tubs of ice-cream should slide out quite easily. Cut the ice-cream into discs.
Put the first disc onto the sponge then layer the ice-cream, alternating the flavors, until the bombe is as tall as you like but you must allow at least 2-2.5 inches spare so it will fit comfortably into the oven. Also take into consideration that it has to fit upright into your freezer.
Press together firmly and put into the freezer immediately for at least 20 minutes or until it is rock-hard. As soon as the ice-cream goes into the freezer (or 20 minutes prior to your estimated time of cooking), turn the oven to very hot, 425 to 450 degrees F.
Just before you remove the ice-cream from the freezer start making the meringue. Place the three egg whites, (don't forget to keep half an eggshell), into a clean mixing bowl and whisk until they form soft peaks. Gradually add the caster sugar into the bowl continuing to mix well until the sugar is dissolved.
With a hard, flat spatula, smear the meringue very quickly to completely cover the ice-cream and sponge. Leave enough meringue to mound on the top for presentation. Place in the very hot oven straight away and cook for only 3 - 5 minutes or until the meringue has lightly browned - so keep a close eye on it.
Some people just pop sparklers in the top to serve. The following 'flaming' special effect is spectacular. Poke half an eggshell that has been washed and dried into the top of the bombe. Be careful that the shell does not crack as it will be the reservoir for the brandy.
Heat a small saucepan and pour 3 tablespoons of brandy into the hot saucepan. Remove from the heat as the warmth from the hot saucepan will be enough to heat the brandy. Set a flame to the alcohol and as it burns tip it into the eggshell and the flaming brandy will spill over the entire bombe. The result is spectacular! Serve straight away and cut with a knife dipped in hot water.
When cutting the discs of ice-cream use a big knife that has been dipped into hot water and cut quickly. This will slice the ice-cream easily and evenly.
Take the height of your freezer and oven into consideration before stacking the ice-cream layers.
Remember safety in the kitchen because you are working with flames and it is important to take care.
For a breathtaking effect serve with the lights dimmed!
