Potatoes in the Half Shell

Ingredients

Directions

Wash well and bake six large potatoes. When done cut in halves, scoop out the inside, mash, add three tablespoons of butter and as much cream as the potatoes will take up, add salt and pepper, and the whites of two eggs, well beaten. Beat until light and creamy. Refill the shells with this mixture, sprinkle grated cheese over the top and bake about ten minutes in a hot oven. — Mrs. Charles Melrose.
