For an extra layer of flavor, consider soaking the raisins in warm rum or apple juice for 30 minutes before adding them to the filling. If you prefer a larger pie, you can bake the filling in a 10-inch pie crust. Increase the baking time by approximately 30 minutes, or until the center is set. Serve the mini pies with a dollop of whipped cream, a sprinkle of cinnamon, and toasted coconut flakes for a delightful finishing touch.
