I can give you directions to make an oven baked corned beef as I suppose that is what you will use to prepare this dish. Place corned beef in a large flat baking pan and add water to depth of ¼ inch. Cover the pan with a lid or foil and place it in a preheated 300 degree oven for 3-4 hours. Once cooked, retrieve the liquid and pour it in a kettle with another 3 cups of water and bring to a boil. Add vegetables like potatoes, shallots, bay leaves and carrots and cook in the liquid for about half an hour. Slice corned beef and serve with horseradish sauce. Serve the potatoes and carrots separately in a bowl. Bon Appetite!
