The best tasting corned beef ever. I don't always add the cabbage, onions and potatoes; I prefer to make a separate casserole, as I am not fond of boiled cabbage. Either way, it's the glaze that makes this corned beef so delicious. I don't remember where the recipe came from, but I have been making it for many years. I buy the largest size brisket I can find, since the leftovers are amazing on rye bread glazed with the mustard.
