Drain beans and cook in a pot of unsalted water for 30 minutes.
Drain, rinse under running water, and set aside.
Arrange all ingredients, including beans, in a large pot. Cover with water and bring to a boil on medium heat. When the liquid boils, lower the heat and cook for one hour or until the beans are soft.
Remove the bay leaf and use an immersion blender to cream the vegetables in the broth. First, if you like, remove some of the beans for other uses.
Taste and adjust the salt if needed.
Bring the broth to a boil, submerge the jujubes, and cook for a few minutes. Serve the pasta in the warm bean broth.
