You will need
¾ cup (180 ml) seedless raisins
½ cup (125 ml) dark rum
3 extra large eggs
2 T (30 ml) sugar
1 t (5 ml) lemon juice
½ cup (125 g) castor sugar
2 t (10 ml) maizena (cornflour)
2 cups (500 ml) fresh whipping cream
Measure raisins into a sieve or colander. Pour boiling water over to soften them.
Decant raisins into a small mixing bowl, pour over the rum and allow to soak for at least 30 minutes.
Now you need a medium size spotlessly clean glass mixing bowl for the egg whites and a smallish saucepan for the yolks.
Start with the yolk custard first.
Add 1 cup (250 ml) of the cream to the yolks and 2 T of sugar.
Stir over medium/low heat with a wire whisk until thick, do not boil.
As soon as the custard heavily covers the back of a metal spoon it is ready. Remove from the heat and place the saucepan into a sink with cold water to bring the temperature down quickly, while stirring now and again.
Beat the egg whites in the mixing bowl with lemon juice to soft peak stage. Gradually beat in the castor sugar little by little until the mixture is thick and shiny. Sift over and mix in the maizena.
Immediately, using the same beaters, whip the remaining 1 cup (250 ml) of cream to soft peak stage.
Fold the cooled custard into the whipped cream followed by the beaten egg white.
Finally, fold in the raisins and any remaining rum.
Pour into a suitable freeze stable container.
