Loosely related to a dessert from the English-speaking islands of the West Indies, this makes a wonderful and legal winter fruit pudding. Despite its richness, it has next to no fat and, if you use eggs modified with omega 3 oil, it couldn't be more nutritionally sound. Mash 4 large bananas (if anything, slightly overripe) with 200 g caster sugar, 6 tablespoons mandarin juice and 3 tablespoons white rum. Separate 4 eggs and beat the whites with a pinch of salt until they stand in stiff peaks. Fold the whites through the banana mixture gently and turn the mixture into a serving dish or dishes. Chill for several hours until set. Meanwhile, beat the egg yolks with 3 tablespoons of sugar until thick and creamy. Tip the mixture into the top of a double boiler or a basin over simmering water, add 210 mL of mandarine juice and whisk over a gentle heat until it reaches coating consistency. Don't let it boil. Chill for several hours. Serve with the pudding.
