Main Points :

• Roll out the puff pastry and pierce it using a fork or a docker.
• Place it between 2 greased baking sheets so that it will remain flat and regular during cooking.
• Repeat this operation with another rolled out pastry and bake at 180°c for 25 minutes. When finished, leave them to cool on a cooling rack.
• Cut the baked pastries into 3 equal parts using a sawing knife. These rolled out pastries will be the 3 layers of pastry necessary to build the mille-feuilles
