This tangy relish is the pride and joy of the kids at the Christian Cooperative Preschool in Reading, Massachusetts. "They've made it every year since the school opened 30 years ago," says Lynda Z., whose daughters attended CCP. "That baby jar the kids bring home isn't nearly enough to go around, so we make a batch at home with our locally grown berries."
Make this dish a day ahead of time, so the fruit juices and sugar combine. Wash all of the fruit. Cut the oranges and apples into chunks, leaving on the orange rind and apple peel (do remove the seeds and apple cores). Coarsely chop the cranberries in a blender, food processor, or meat grinder--be careful not to over process--and transfer them to a large bowl. Next, process the oranges and then the apples, adding both to the cranberries. Stir in the sugar, mixing well. Chill the relish in a covered container until you're ready to serve it. Makes 6 cups.
