Cut the puff pastry using a round pastry cutter with 16 cm diameter. Place it in a round oven dish of the same size and cover the bottom with greaseproof paper, pressing it against the walls and bottom surface. Add another layer of greaseproof paper over the pastry and add dried beans as weights, so that the pastry doesn’t puff up too much during baking. Place this in an oven preheated to 180°C for 18 min. After baking, leave it to cool for 5 minutes at room temperature.
