This recipe makes enough pastry to line a 23cm (9 inch) round, 3cm (1¼ inches) deep loose-bottomed tart tin (pan). There will be leftover pastry for small decorations, however, if you are making a lattice pie or a fully covered pie, remember to make a double quantity. The amount you need depends on how intricate you become with your piecrust designs. Any leftover pastry can be wrapped in clingfilm
