Mix quark, yoghurt and honey. Season with vanilla flavouring. Wash the lemon balm and shake dry. Cut out 4 melon balls. Remove the remaining flesh from the skin and puree finely.
Put melon balls alternating with lemon balm leaves on a wooden skewer. Fill the quark into a bowl, spread melon puree on top and decorate with lemon balm. Place the melon skewer on the rim.
