Makes about 3 cups, serving 2.
In a heavy saucepan cook the onion, the garlic, the gingerroot, the carrot, the celery, and the thyme in the butter over moderately low heat, stirring, until the onion is softened. Add the parsnips and the broth, bring the liquid to a boil, and simmer the mixture, covered, for 15 minutes, or until the vegetables are very tender. Purée the soup in a blender and return to the pan. Stir in the nutmeg, enough water to thin the soup to the desired consistency if necessary, and salt and pepper to taste.
