For the pickled heart cherries, check the heart cherries (rot or tarnished), wash well and place on a towel to dry. Caramelize sugar in a saucepan, deglaze with vinegar and pour red wine, let it reduce a little and then pour orange juice and port wine.
Add cinnamon stick, cloves and star anise and let marinate for about 12 – 15 minutes. Add the dried cherries to the hot marinade, bring to the boil briefly, fill into Rex jars and seal the pickled heart cherries.
