Rub the roast liberally with olive oil, or even better, bacon grease (handles high temps better) In a HOT cast iron skillet, fry it fast and hot past the point of browning to almost slightly burnt. Let sit for ten minutes. Coat the roast in one packet of Schilling or McCormick Stew Seasoning. (Or lipton onion soup mix if you can't find the stew packets, add some rubbed sage, a pinch of cayenne, and a pinch of ground oregano)
Place roast in the bottom of the crock. Add one bottle of dark beer, (or a cup and a half of burgundy) three or four sliced cloves of garlic, 6-10 juniper berries, a tablespoon of Worcestershire, and a teaspoon of cracked black pepper. Fill the crock pot with water half way up the roast.
Set on low and leave the house for 6 hours.
Come home and bask in the glory.
