Boil a sparerib, after removing all the fat and cracking the bones, until tender; remove the scum as it rises, and when tender season with salt and pepper; half an hour before time for serving the dinner thicken the gravy with a little flour. Have ready another kettle, into which remove all the bones and most of the gravy, leaving only sufficient to cover the pot half an inch above the rim that rests on the stove; put in the crust, cover tight, and boil steadily forty-five minutes. To prepare the crust, work into light dough a small bit of butter, roll it out thin, cut it in small, square cakes, and lay them on the moulding-board until very light. No steam should possibly escape while the crust is cooking, and by no means allow the pot to cease boiling.
