Place the flour and butter into a food processor and process it until it resembles fine breadcrumbs. Slowly adding the iced water until a smooth dough forms. Knead the dough into a ball on a lightly floured surface. Wrap in plastic wrap and place it into the fridge for at least 30 minutes.
Press a piece of baking paper (greaseproof paper) onto the top of the pastry and then fill the base and sides with baking beads. Bake the pastry for 20 minutes in a 180 degrees celsius (fan-forced) oven. Remove the weights and baking paper, turn the temperature down to 160 degrees celsius (fan-forced) and bake for a further 15 minutes or until golden.
