Brown: Heat oil in a large skillet over medium-high heat. Add corned beef and brown on both sides, about 5-7 minutes. Transfer corned beef and pan drippings to a roasting pan. Bake: Preheat oven to 300°. Pour wine over corned beef. Cover tightly with foil and bake for 6 hours. Remove from oven, cool and slice.
Serving Option: For a delicious accompanying sauce, simply pour the cooking liquid into a saucepan and bring to a boil over medium-low heat. Simmer for about 15-20 minutes or until mixture is reduced by half and is a thick syrupy consistency. Season to taste with salt and freshly ground black pepper.
