Ingredients

4 medium sweet potatoes
2 teaspoons salt
4 lemons washed and very thinly sliced, crosswise (do not peel)
2 cups brown sugar
1 stick butter (8 tablespoons)

Directions

Preheat oven to 350 degrees. Mix brown sugar and salt. Remove seeds from sliced lemons. Butter a 9-by-9-by-2-inch square baking dish (or equivalent). Peel sweet potatoes and slice crosswise 1/4-inch thick.

Place a layer of sweet potatoes in baking dish. Sprinkle with about 4 tablespoons of the brown sugar mixture and then place a lemon slice on each sweet potato slice. Put a dot ( 1/4 teaspoon) of butter on each lemon slice. Repeat until all sweet potato slices are used. End with a layer of lemons, dotted with butter and sprinkled with remaining brown sugar mixture.

Cover baking dish with foil or lid and bake at 350 degrees for 1 hour. Remove cover and leave in oven until top layer of lemons browns slightly. Good hot, at room temperature or cold. Serves 4 to 6.
