In a large mixing bowl, add all the mincemeat ingredients and mix well until totally combined.
Transfer to an airtight container and leave to marinate in the fridge overnight.
The next day, preheat your oven to 170°c(340°f) or 160°c(320f) if fan assisted.
Take your chilled pastry, and working in small batches roll out to about 3mm thickness.
Using a round cutter that is slightly larger than the base of your tins, cut the dough, ensuring to cut close together for less pastry trimmings.
Gently knead any leftover pastry into a ball and let rest for a few minutes.
Take the discs of pastry and gently place into the base of the prepared tins.
Mix up the mincemeat well and fill the pastry with generous teaspoons of mincemeat.
Take the pastry trimmings and roll out thinly. Cut with the star shaped pastry cutter and place a star on top of each mince pie.
Brush the star lightly with milk and bake in the preheated oven for 12-15 minutes.
Allow to cool for a minute or two before removing from the tins.
Repeat the previous steps until all the pastry and/or mincemeat is finished.
