In a large soup pot bring the water, broth and split peas to a boil. Add the yams, celery, carrots, onion and spices. Simmer for one hour or until split peas and veggies are fully cooked and tender, stirring occasionally. Remove bay leaves before serving. We like our soup to be chunky but if you prefer a creamy smooth soup you can put it in a blender in batches and process until smooth. This soup freezes well.
