Cut away any pastry that hangs over the edge of the dish.
Prick the pastry all over with a fork.
Chill until required.
Lay a large piece of parchment over the raw pastry, making sure all the edges are covered.
Scatter the ceramic baking beans (or rice or flour) over the parchment, spreading them evenly over the surface.
If the pastry is to have a cold filling, bake for 15-18 minutes then remove from the oven and carefully lift the parchment and contents off the pastry. Return the pastry to the oven and cook for a further 5-6 minutes. Fill according to your recipe.
If the pastry is to be filled and cooked again, bake for 10-12 minutes then remove from the oven, carefully lift the parchment and contents off the pastry and return it to the oven and cook for a further 4-5 minutes without browning too much.
