01 - Preheat the oven to 350°F. Unwrap the Camembert and place it back in its wooden box or a small ovenproof dish.
02 - Using a sharp knife, score the top surface of the cheese in a crisscross pattern.
03 - Spoon the cranberry jam evenly over the top of the cheese. Optionally, scatter rosemary leaves and chopped nuts over the jam. Sprinkle with freshly ground black pepper.
04 - Bake in the preheated oven for 12 to 15 minutes until the cheese is soft and molten in the center.
05 - Remove carefully and serve immediately with sliced baguette or crackers for dipping.
