In a large bowl combine marinade ingredients and beef. Chill, covered, overnight. Drain beef, reserving marinade and vegetables separately; pat beef dry and season with salt and pepper.
Preheat oven to 275/F. Cover bacon and rind with cold water, bring to a boil and simmer 3 minutes. Drain. In a large casserole set over moderate heat cook bacon lardons in butter and oil, stirring often, until golden. With a slotted spoon transfer lardons to paper towels to drain.
In casserole over moderately high heat brown beef in bacon fat, in batches. Pour off all but 1 tablespoon of fat from casserole. Add reserved vegetable mixture and cook, stirring, for 5 minutes. Add reserved marinade liquid, tomato paste, reserved bacon rind and salt and pepper, bring liquid to a boil and cook in oven, covered, 3 hours. Skim fat from stew and drain meat and vegetables, reserving cooking liquid. Return liquid and meat to casserole.
Meanwhile make vegetable garnish: In a skillet cover onions with water, add 1 tablespoon of butter, sugar and salt and pepper to taste. Simmer onions until almost tender. Raise heat to high and reduce cooking liquid to 2 tablespoons. Continue to cook onions, shaking pan over heat, until golden brown and glazed. In a skillet set over moderately high heat, melt remaining butter and add mushrooms and salt and pepper to taste. Cook mushrooms, tossing often, for 7 minutes, or until firm. Add the onions and mushrooms to the casserole. Bring liquid in casserole to a simmer and add enough Beurre Manie, bit by bit, stirring constantly, to lightly thicken sauce.

To serve: spoon meat and vegetables into shallow serving dishes and garnish with croutons.
