The pies can be reheated in an air fryer at 160 C for 10-15 minutes, or until steaming hot all the way through. They can also be reheated in an oven. Place the pies on a tray and cover with aluminium foil. Bake at 180 C for 12-15 minutes, or until steaming hot all the way through. Avoid using a microwave to reheat, as the pastry won't crisp again.
