Hi..You can peel the sweet potato,cut in chunks and cover with water.Boil until tender,drain off water and put on butter.You can also wash the sweet potato and rub with a little shortening and bake in a 350 degree oven until done.Cut and butter.Some ,including me,cut up peeled potato,boil until almost done.Put in a baking pan and cover with butter and a little brown sugar or white and cover with marshmallows.Bake at 300 until done and marshmallows are melted.Delicious!! Hope this helps..laVerne
