- Melt butter over medium heat in a soup pot. Add onion and celery, and sauté 5 minutes until onions are fragrant.
- Add fresh ginger, garlic, cinnamon, ground ginger, and cayenne pepper, and cook 1 minute more, stirring constantly to prevent sticking. Stir in sweet potatoes, pour 4 cups of broth over vegetables, add salt, and increase heat to bring soup just to a boil. Reduce heat to medium-low, cover, and simmer 10 minutes.
- Add apples, and simmer another 10 minutes or until potatoes are very tender. Remove and discard celery. Stir in syrup, if using, and purée soup with immersion blender. (Or cool slightly and purée in batches in a blender or food processor.) Adjust seasonings to taste.
