Bring 75 g sugar and 6 tbsp. water to the boil. Simmer until the sugar is dissolved. Remove from the stove.
Beat the egg yolks and 1sp. cinnamon until creamy with the whisks of the hand mixer. Add the sugar syrup first drop by drop, then in a thin stream. Continue beating the egg yolk mixture until it gets cold.
Whip the cream until stiff and fold into the egg yolk mixture. Pour the parfait mass into glasses or dessert bowls (each containing approx. 150 ml) and freeze covered for at least 4 hours.
Wash, halve and stone the plums. Cut the vanilla pod lengthwise. Scrape out the pith. Boil up wine, 100 g sugar, 1 pinch cinnamon, clove and lemon peel while stirring. Add the vanilla pulp and pod and simmer until the sugar has dissolved.
Fold in plums and simmer covered for about 15 minutes. Serve red wine plums hot or cold with the parfait.
