Preheat the oven to 200°C (gas mark 6, 180°Fan) and grease a cupcake tin with oil or butter.
Unroll your ready-made puff pastry sheet and use a sharp knife or pizza cutter to slice it into 20 squares.
1 Puff Pastry Sheet
Gently press each pastry square into the greased moulds, shaping them to form little cups.
Add a small amount of Dijon mustard onto the base of each pastry. Top with a piece of Brie, then a teaspoon of cranberry sauce, salt and black pepper. Then top with pieces of rosemary.
100 g Cranberry Sauce, 200 g Brie, 20 tsp Dijon Mustard, Salt, Black Pepper, Rosemary Sprigs
Bake for 15 minutes, or until the pastry has puffed up and turned golden brown and the Brie is melted and bubbly.
Shortly after taking them out from the oven, I like to loosen the pastry with a gentle twist to help it detach from the mould and to stop the caramelised cranberry sauce from sticking to the cupcake tin.
