For a richer, more aromatic sauce, consider using freshly squeezed orange juice. You can also add 1-2 teaspoons of orange zest along with the cranberries for an intensified citrus note. A pinch of ground cloves or a whole star anise can be added during the initial cooking phase for more complex spice, remembering to remove the whole spices before serving. To prevent the cranberries from sticking or scorching, ensure regular stirring as specified. The sauce will thicken further as it cools, so don't overcook it to an overly jammy consistency in the slow cooker.
