Here's Mrs. Bracken's recipe for Sweep Steak -- "So called because a couple of seasons ago, this recipe swept the country":
4 - 6 servings
2- to 3-pound round steak or pot roast
both 1-ounce packets in the package of onion-soup mix
Put the meat on a sheet of aluminum foil big enough to wrap it in. Sprinkle the onion-soup mix on top of it, fold the foil, airtight, around it, put it in a baking pan, and bake it at 300 degrees for three hours or 200 degrees for nine hours, it really doesn't matter. You can open it up, if you like, an hour or so before it's done, and surround it with potatoes and carrots.
