1 Place corned beef in large pot or Dutch oven and cover with water. Add the spice packet that came with the corned beef. Cover pot and bring to a boil, then reduce to a simmer. Simmer approximately 50 minutes per pound or until tender.  Add whole potatoes and carrots, and cook until the vegetables are almost tender.
Set a timer for proper roasting times. The following instructions should help you ensure the corned beef will be done in time for dinner. If you are using a bag, cook for 2.5 to 3 hours for a 2 to 3 lb (0.9 to 1.4kg) brisket. Cook for 3.5 hours for a 3.5 to 5 lb (1.6 to 2.3kg) brisket.
