On the day before it is to be cooked, cut 4 slices of bacon into 1" pieces and chop fine 1 tablespoon of the onion which has been soaking in the vinegar. Cut holes in themeat 1 or 2 inches apart and stuff bits of the bacon and chopped onion into the holes. Put the meat back into the solution, add 1 tablespoon whole cloves and 1 teaspoon whole allspice. Bake the meat as a pot roast in part of the solution, until tender. Use more of the solution, adding sugar to taste, in making the gravy which will be almost black. ----
