Drain the cherries and collect the juice. Drizzle the cherries with amaretto and leave to stand. Boil up the cherry juice, red wine and sugar. Wash and slice the lemon. Let cinnamon stick, star anise, lemon slices and infusion bag steep in hot wine for about 10 minutes.
Pour 1 tablespoon of marinated cherries into each glass. Fill with hot mulled wine and serve.
