Australian Mince Pies

Preheat oven to 190 degrees C. Heat a glug of oil in a pan and brown mince. Add remaining filling ingredients, except peas, and allow to simmer for 30 minutes or until butternut is soft and sauce has reduced. Stir through peas and allow to cool. Roll out pastry and cut out 12 rounds for pie bases. Line a well-greased 12-cup muffin pan with pastry (it should come up the sides and overlap edges slightly). Fill each pastry cup with a tablespoonful of filling. Roll out remaining pastry and cut out round pie lids using a pastry cutter. Brush with egg and cover filling. Press down to seal edges and trim edges with a knife. Pierce a small steam hole in the lid of each pie and decorate as you like. Bake for 25-35 minutes or until pastry is cooked through and golden.
