Add the piece of corned beef and the water to a glass baking dish with sides. Cover securely with foil and cook in a 350 degree oven for 2½ -3 hours and remove from oven for glazing
Mix apricot jam, brown sugar and soy sauce together and cover the meat with ¼ of the mixture
Cook uncovered for 10 minutes
Remove and add another ¼ of the glaze to the meat and return to the oven for 10 more minutes, repeat once more
If the meat is is cooked to your desired tenderness you can remove it and allow it to rest of 5-10 minutes, if not, glaze and cook for 5 more minutes - keep an eye on it as to not burn the glaze.
