Wash and pick over cranberries, discarding any that are soft. Bring water to a boil; add berries. Cover and cook over medium low heat until berries have burst outer skin.

Add sugar and boil a few minutes longer. If desired, cranberries may be strained before sugar is added. A few tablespoons of freshly squeezed orange or lemon juice may be added along with a little grated citrus peel, if desired. A tablespoon of frozen orange concentrate is also a nice addition.
