100 grams crisp Italian style biscuit eg biscotti, savoiardi, or amaretti
¼ cup sweet wine, Vin Santo, Marsala or limoncello
2 medium eggs, separated
40 grams caster sugar
finely grated zest of 2 lemons
¾ cup cream
Roughly crush the biscuits and sprinkle with the wine.
Whisk the egg yolks with the caster sugar until pale and thick and stir in the lemon zest.
Beat the egg whites until stiff but not dry. Whip the cream to soft peaks. Using a large metal spoon, fold a quarter of the egg whites into the yolk mixture to loosen it and then fold in the remainder. Fold in the whipped cream along with the biscuits.
Divide between 6 ramekins or glasses and freeze for about 2 hours. The mixture is not meant to be solid. Serve with extra biscuits if desired.
