Lay the two puff pastry rectangles on a baking tray and place in the oven to bake. After 10 minutes, turn down to 160⁰C/gas mark 3. Cook for another 30 minutes, then test the pastry by carefully lifting up one of the rectangles and tapping the bottom. If it feels crisp, remove the pastry from the oven. If it feels soft, reduce the temperature to 140⁰C/gas mark 1 and bake for another 10 minutes or until crisp
