The mince filling can be made 1-2 weeks ahead and kept in an airtight container in the fridge — the flavour only gets better. The brandy is optional: swap it for the same amount of orange or apple juice for an alcohol-free version. Note that the filling contains almonds and pine nuts. Store baked pies in an airtight container at room temperature for up to 3 days, and dust with powdered sugar just before serving.
