Puree of Oatmeal or Wheaten Grits

Put four quarts of water or broth into a saucepan, let boil, and dredge in a shower while stirring one pound either of oatmeal or wheaten grits; let cook for thirty minutes, pass it through a tammy, and add either more water or some broth, so as to obtain a clear puree fit to be drank easily from a cup, without using a spoon; a little salt and butter may be added.
