In a bowl, mix the yolks and sugar. Place the bowl in a bain-marie (double boiler) and mix with an electric mixer until the mixture becomes pale and frothy. Add the wine and cook without ceasing to whisk until frothy cream. Place the fruit in ramekins, top them with zabaglione and broil in the oven 2 to 3 minutes. You can decorate a scoop of ice cream, if desired.
You can use other raw or cooked fruit (nectarines, strawberries or raspberries...) and replace the ice cream with sorbet. For the alcohol, some prefer to use Marsala or spirits, mixed or not: Whisky, Armagnac or Rum. You can add vanilla, cinnamon or cardamom.
