Step 1

In a saucepan over moderate heat, combine the sugar, red wine and cinnamon stick; bring to a boil. Reduce the heat and simmer for 3 to 4 minutes, stirring occasionally, until the sugar is dissolved and the wine is reduced slightly.

Step 2

Add the cranberries and zest. Simmer for 5 to 10 minutes, or until the cranberries are soft and the sauce has thickened. Serve at room temperature or chilled. (More and more, I simmer for 5 minutes; then turn it off. This preserves some of the texture of the cranberries.)
