Nordic Winter Vegetable Soup

In a large pot, heat the oil. Add the onion, leeks and garlic and cook over moderate heat, stirring occasionally, until tender, about 5 minutes. Stir in the barley. Add the vegetable broth, water, thyme and bay leaves and bring to a boil. Add the celery root and parsnips and season with salt and pepper. Simmer over moderately low heat until the barley and root vegetables are tender, about 40 minutes.

Stir in the spinach and nutmeg and simmer for 5 minutes. Season the soup with salt and pepper and serve in deep bowls.
