This is a favorite recipe of mine. I've made it for every Thanksgiving since Michael was a baby. It needs to chill for 24 hours before you serve it, so plan accordingly!
1 (12-oz) bag cranberries, fresh
1 whole cinnamon stick (or ½ teaspoon ground cinnamon)
1 cup apple cider
1 cup sugar
Place apple cider over medium heat in a medium-sized saucepan. Add cinnamon stick and sugar and stir until dissolved. Bring to near-boiling. Add cranberries. Turn down heat and simmer, stirring occasionally, until about one fourth of the cranberries are burst, approximately 10 minutes.
Remove from heat.
Chill at least 24 hours to allow flavors to blend.
