Grease a 12 hole cupcake/muffin tin.
Roll out your chilled pastry until about 3mm thick.
Cut out 12 circles large enough to line the base of one hole and up the sides, approx a 10cm cutter should work and it depends on the size of the holes.
Place the pastry in the holes and fill them with 1 1/2 tsp of cherry mincemeat.
Beat an egg (or use the leftover egg if you have enough) and brush over the top of the pastry.
Re-roll the pastry if needed and cut out 12x 7cm lids and place on top by pressing round the edges to seal.
TOP TIP: Don't glaze the tops with egg as it leaves odd looking marks.
Cut a hole in the top and place in the oven for 15-20 minutes until the pastry feels crisp.
Remove from the oven and leave to cool completely before removing from the tin.
Dust with extra icing sugar before serving.
