1 cup sugar

4 cups cranberries (pick out any stems)
Place all in a medium saucepan. Cook and stir over high heat until it comes to a boil. Reduce heat and let cook an additional five minutes, stirring occasionally. Pour into a serving dish and let cool.
Here is a nice list of optional additions: Pecans, orange peel, raisins, currants, blueberries, cinnamon, nutmeg, allspice.
