This tart and refreshing relish is an excellent companion not only to the Thanksgiving turkey, but to any meat or fowl. Since you use the whole orange, including the rind, it is important to allow the relish to mellow for at least 2 days before serving. Pick over: 1 12-ounce package cranberries Cut into eighths and remove the seeds from: 1 orange, unpeeled Place half of the cranberries and half of the orange in a food processor fitted with the steel blade and pulse until the mixture is evenly chopped but not pureed. Transfer to a medium bowl. Repeat with the remaining cranberries and orange. Stir in: 1 cup sugar Cover and refrigerate for at least 2 days or up to 2 weeks. Serve chilled or at room temperature.
