Remove the corned beef from all its packaging and rinse under cold water to remove any left- over pickling spices stuck to the meat.
Place in a 9x13-inch baking pan, fat side up, and add ¾ cup of water.
In a small bowl, combine the sauce ingredients. Spread ¾ of the mixture over the top of the beef. Cover tightly with aluminum foil.
Bake for 3 to 3½ hours. Remove pan from the oven.
Turn oven to broil. Remove foil and brush the beef with remaining glaze. Return to oven and broil for approximately 5 minutes, until glaze begins to caramelize.
Remove from oven and cool fully before slicing against the grain.
Variation: This recipe works great with mini hotdogs or sliced hotdogs. Add the sauce ingredients to a pot and mix well to combine. Cook over medium-low heat until heated through. Add hotdogs and bring to a simmer. Cover and cook for 10 minutes. Huge hit with the kids!
