You will need 2in diameter patty tins, which are available in trays of 12. Brush one sheet of filo pastry lightly with oil and cut into 2.5 inch squares. Take one square and overlap with another square placed diagonally on top. This means you end up with 8 points like a star. Press this shape gently into the patty tins until all the trays are filled up. Bake in a preheated oven at l90 °C/375°F/Gas 5 for 7-10 minutes until golden brown. Allow to cool and store for up to a week in an airtight container until ready to use.
