Clean and wash 1 large hare or 2 small rabbits, and cut into serving pieces. Allow pieces to stand 24 to 48 hours in a cool place covered in a marinade made of: 2 cups vinegar, 1 cup water, and 1 cup claret. Add 2 large sliced onions, 1 Tbsp salt, 1 tsp black pepper, 1 tsp mustard seed, 6 bay leaves, and 8 whole cloves to marinade. Turn pieces every 12 hours.
When marinade is finished, wipe pieces dry, dredge in flour, and sauté in 1/3 cup of fat in a Dutch oven until browned on all sides. Drain off the fat.
Strain the marinade, dilute it with 1/2 cup of water, add 1 Tbsp sugar and pour over meat. Bring the whole to a boil and cover tightly. Simmer about 40 minutes or until meat is tender. Season again with salt and pepper.
Take pieces out of pot and place on hot platter, thicken sauce with flour to a gravy, and pour over rabbit.
Serve with noodles and browned bread crumbs.
