For the topping:
* 3 tablespoons unsalted butter
* 3 McIntosh or Macoun apples, peeled, cored, and cut into eighths
* 3 tablespoons light brown sugar
I substitute caramelized apples for the traditional marshmallows on top of this sweet potato puree. It's delicious and adds a wonderful natural sweetness. Of course, you can always make this with marshmallows for the children!
