- 2–3 tablespoons iced water
Process the flour and butter in a food processor until the mixture resembles fine breadcrumbs. While the motor is running, add enough iced water to form a smooth dough. Knead very lightly then wrap the dough in plastic wrap and refrigerate for 30 minutes. When ready to use, roll out on a lightly floured surface until 3mm (1/8 in) thick. Makes 350g (12 oz), which will line up to a 25cm (10 in) pie dish or tart tin.
