If using brandy, open jar of mincemeat, pour in, and mix with a long spoon until combined. this step is optional.
Fill each base with 1/2 tablespoon fruit mince, ensuring not to overfill as it will bubble out during baking.
Sprinkle more flour onto the surface and roll out the second half of dough until it's 4mm-5mm thick and approx. 30-35cm (11.8 inch - 13.7 inch) across.
Take a smaller round 6cm (2.3-inch) cookie cutter and cut out shapes for the tops, you should get 24 tops and more if you re-roll all the excess dough. NOTE: if you use a slightly different-sized cookie cutter, you'll get more or fewer tops, just be sure you have enough to match the bases.
Take a small round piping tip/nozzle (size 15) and cut out the centers of the pastry tops, similar shape of a doughnut.
Place pastry tops on pies to cover filling, pressing down slightly around the edges to seal.
Place pan in refrigerator to chill pies for 15 minutes.
Remove from fridge and lightly brush pastry tops with milk.
Bake for 15-20 minutes or until lightly golden all over, some will be pale and that's ok, you don't want to overcook.
Remove and cool in pan for 5 minutes.
Transfer to a wire rack and dust pies with powdered sugar.
Serve warm or cool completely on wire rack.
Store in an airtight container, at room temperature, for 5 days.
Enjoy!
