Boil soft two large or four small sweet potatoes, mash smooth while very hot, free of strings and eyes, add a pinch of salt, then rub well through three cups of sifted flour. Rub in also a generous handful of shortening, then wet up soft with two eggs beaten very light, and sweet milk. A little sugar also if you have a sweet tooth–but only a little. Roll to half-inch thickness, cut out with small cutter, lay in warm pan, and bake brown in a quick oven.
Soda and buttermilk can take the place of eggs and sweet milk–in which case the sugar is advisable. Mix the soda with the milk–enough to make it foamy, but no more.
