Cranberry-pomegranate cider is a sweet twist on a homey classic. Make a single serving for a quiet afternoon or a batch in the slow cooker for winter entertaining.
Combine all ingredients in a small saucepan. Bring to a simmer. Lower heat slightly and allow to cool for at least 10 minutes.
Remove from heat and remove piece of ginger. Pour into a mug. Garnish with fresh cranberries or apple slices, if desired, and enjoy while hot.
