1 1/2 C. green or brown lentils

1/2 lb. celery root, peeled and cut into 1/4 cubes (1 C.)

4 T. olive oil

1 medium onion, coarsely chopped

1 medium leek, white part only, cleaned and cut into 1/4 inch slices (1 cup)

Cover the lentils with a generous amount of water in a 6-quart heavy bottomed pot. Bring to a boil and keep a steady boil for 15 minutes. Drain and set aside

Heat the olive oil in the soup pot; add the celery root, onion, leek, shallots and garlic. Cover and braise over medium heat for 10 minutes.

Add lentils to the vegetable mixture. Pour in the broth, season with salt and pepper and bring to a boil. Reduce the heat, and cook at a gentle boil, partially covered, for 1 hour. During the last 5 minutes of cooking, add the watercress.

Puree the soup in batches in a blender until very smooth. Add more broth if the soup is too thick. Whisk in the mustard and vinegar.

Just before serving, reheat the soup, taste and correct seasoning with more salt and pepper. Ladle the soup into hot soup bowls or plates. Dribble the soup with heavy cream and sprinkle with chopped celery leaves if you wish.
