Use the recipe for pastry and mincemeat or use shop bought pastry and mincemeat. You will need approximately 300g of mincemeat. Grease a bun tin with butter. Roll the pastry out and cut out rounds which will fit into your chosen size tin.
Place the pastry rounds into the prepared tin and add a teaspoon of mincemeat to each pastry case. (If you are doing deep filled pies allow more mincemeat per pie.)
Roll out pastry again and cut out enough rounds to cover the top of each pie. Bake in a preheated oven for 20 - 25 minutes or until the pastry is golden. Dust with icing sugar if desired.
