Sweet Potato Pone
Stir together till very light and white, three quarters of a pound of fresh butter, and three quarters of a pound of powdered white sugar, adding two table-spoonfuls of ginger. Grate a pound and a half of sweet potato. Beat eight eggs very light, and stir them gradually into the butter and sugar, in turn with the grated sweet potato. Dissolve a tea-spoonful of saleratus or soda in a jill of sour milk, and stir it in at the last, beating the whole very hard. Butter the inside of a tin pan. Put in the mixture, and bake it four hours or more. It should be eaten fresh, cut into slices.
