3 pounds sweet potatoes
4 tablespoons butter
1/2 cup light brown sugar
1/2 cup maple syrup
1/2 teaspoon salt
1/2 teaspoon cinnamon
1/8 teaspoon cloves

Preheat oven to 350 degrees F.

Peel sweet potatoes and cut into thin slices.

Melt butter in 10-inch cast iron skillet. Stir in brown sugar, maple syrup, salt and spices. Remove 1/2 cup of this mixture. Arrange a layer of sweet potatoes in concentric circle in the syrup in the bottom of the skillet and up the side. Continue layering until you have used about 1/3 of the potatoes. Drizzle 1/3 of the reserved syrup over the potatoes. Repeat to make 2 more layers. Cover with cast iron lid or foil and bake until tender, approximately 55 to 60 minutes.

Loosen edges with spatula and invert onto serving platter. Cut into pie-shaped wedges to serve.
