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.
Bring everything to a boil, cover, and reduce the heat to maintain a steady simmer and cook, more or less undisturbed, until the corned beef is completely tender when pierced with a fork, 3 to 4 hours. Remove the corned beef from the pot and slice across the grain to serve.
