This is a fresh take on traditional cranberry sauce. The flavors are so bright and provide a great balance to all of the heavy dishes on the Thanksgiving buffet. It's also a super-fast recipe to make with no cooking required!
Swap option: If you don't have walnuts, try pecans, almonds or hazelnuts.
Grate the zest from the orange and set aside. Cut off any remaining pith from the orange. Cut the orange into chunks.
In a food processor, combine cranberries, orange chunks, orange zest, apple, and celery and process until finely chopped. Be careful not to process too long because mixture will become mushy. Add the walnuts and pulse until chopped. Stir in the sugar and orange liqueur (if using). Refrigerate until serving time.
