2 eggs
80g sugar (50g if you use lactose-free milk and cream)
250g cream
150g eggnog
150g milk 50g dark chocolate (50% cacao)

Beat the eggs and sugar over a water bath until they form a rose. So beat them until you get a very thick fluffy mixture. Alternatively, you can use a heated food processor.

Stir in the cream, eggnog and milk and chill the mixture for 2-3 hours.

Put the mixture into the ice cream maker.

Just before the ice cream is ready, melt the chocolate and pour it into the ice cream in a fine stream 2-3 minutes before the ice cream is ready.
