Toasted Marshmallow Sweet Potato Pie
This pie is a bit of a time commitment, but what a showstopper! The recipe comes from the Sister Pie cafe in Detroit. Note that you'll need pie weights or a couple pounds of dried beans for blind-baking the crust. Also, if you don't have a broiler-safe pie plate (metal is safest), you will need a kitchen torch to toast the topping. They are quite inexpensive.
One of the egg whites in this pie’s topping remains uncooked. If you are concerned about the risk of foodborn illness, substitute liquid pasteurized egg whites (2 tablespoons per white).
