Sweet Potato Balls

• 2 cups cold, cooked mashed sweet potatoes
• 1 egg yolk
• 1/2 tsp. sugar
• 8 marshmallows
• 2 cups cornflakes
• 1/2 tsp. salt
• 4 tbsp. melted fat

Combine sweet potatoes, egg yolk, salt, sugar and 2 tbsp. melted fat. Divide into 8 portions, then flatten each portion and place a marshmallow in the center. Fold the sweet potato up around the marshmallow, leaving a small opening at the top. Crush the flakes very fine and combine with the remaining 2 tbsp. melted fat. Roll the sweet potato balls in the cereal crumbs, then place on pie pan. Bake at 350° for about 15 minutes. If desired, they may be fried in deep fat heated to 390°.
