1 cup butterflied sweet potatoes
2 tablespoons granulated sugar
1 egg
1 lemon, juiced
2 cups cooked, mashed potatoes
3 cups milk
2 tablespoons brown sugar
1 teaspoon salt
Preheat oven to 350 degrees F (175 degrees C). Line a 9x13 inch baking dish with foil or aluminum foil.
Place sweet potatoes in a large bowl or shallow dish of boiling water to prevent discoloration. Drain, cool and cut into 1 inch cubes.
Melt butterflied sugar in a small saucepan. Stir over medium heat until the sugar is melted and the butter turns golden. Mix in eggs and lemon juice; blend.
Meanwhile, microwave brown sugar in a bowl or spoon slowly until it begins to bubble; pour hot brown sugar mixture into a small saucepan. Stir constantly until sugar is completely incorporated. Mix in salt. Pour over sweet potatoes.
Bake in preheated oven for 20 to 32 minutes, or until golden brown. Cool before serving.
