Beef or Mutton Lobscous

Mince, not too finely, some cold roasted beef or mutton. Chop the bones, and put them in a saucepan with six potatoes peeled and sliced, one onion, also sliced, some pepper and salt; of these make a gravy. When the potatoes are completely incorporated with the gravy, take out the bones and put in the meat; stew the whole together for an hour before it is to be served.
