Wash the salad, dab dry and possibly pluck a little smaller. Mix vinegar, salt, pepper and 1 pinch of sugar. Fold in the oil. Stir the cranberries into the marinade.
Put the pumpernickel on a baking tray covered with baking paper. Cut the cheese into 8 cake pieces and place them on top. Wash the thyme, remove the leaves and sprinkle over the cheese. Bake in the preheated oven (electric cooker: 200 °C/circulating air: 175 °C/gas: level 3) for 3-4 minutes until the cheese melts creamy.
Place the salad leaves as a garnish on 4 plates. Spread marinade over them. Arrange the Camembert taler next to it.
