Rinse cranberries under running water, picking out stems or any berry that is blemished;
In a saucepan over medium heat, bring water and sugar to a boil, stirring constantly to ensure that all the sugar is dissolved;
Add the cranberries and bring back to a boil. Stir occasionally;
Turn heat to medium low and continue boiling another 5 to 10 minutes, or until the cranberries begin to pop (at this point, you may choose if you prefer the sauce smoother or lumpier. Either wait until all the berries pop or remove from heat before they all do);
Turn off heat and let sauce cool completely at room temperature. Then chill for about 3 hours. The sauce will thicken after it's cool.
