Ingredients
1 (6 lb) corn beef brisket
1 medium onion, halved
1 celery stalk, chopped
1 large carrot, chopped
2 garlic cloves, halved
½ tsp peppercorns
For the sauce, combine:
2/3 cup brown sugar, packed
2 tsp prepared mustard
2 tsp ketchup
Directions
In a large Dutch oven four hours before serving, place all ingredients with enough water to cover the meat. Bring to a boil; cover and simmer for three hours or until meat is fork tender. Preheat oven to 350 degrees. Slice meat and arrange in an oven-safe dish. Spread sauce on meat and bake for 20 minutes.
