In a pan, cover the corned beef with cold water and let it stand for 1 hour.
Drain and place the beef back in pan with a bay leaf, garlic, cloves, coriander, seeds, pepper, carrot and onion. Cover with cold water. Add 1 teaspoon of vinegar for each quart of water. Simmer until tender, 30 to 40 minutes per pound.
Let it all stand in liquid for 20 minutes. Drain and pull apart for sandwiches.
