1 9-inch pie shell; unbaked
1 cup cooked sweet potatoes
3 eggs
½ cup dark brown sugar; firmly packed
4 tablespoons unsalted butter
¾ cups half and half
½ teaspoon ginger
¼ teaspoon cinnamon
½ teaspoon sea salt

1. Preheat oven to 350ºF.

4. Make the topping by beating 4 tablespoons butter, 4 tablespoons flour and 4 tablespoons brown sugar together. Sprinkle over pie filling.
