1 stick butter
1 bunch leeks or 1 large onion
6 cups chicken brother, preferably homemade
5 white potatoes, peeled and thinly sliced
Salt and white pepper
1 carton whipping cream
Melt butter in large pot. Wash very well first, then add chopped leeks, using only the white parts. Cook slowly until tender but do not brown. Add chicken broth and potatoes (use food processor or mandoline to slice). Cover and cook over medium heat until potatoes are mushy. Puree in blender or food processor until very smooth. Add salt and pepper to taste. Chill well. When ready to serve, add 1 carton whipping cream. If it is too thick, add a little milk. Mix well and top with finely chopped shallots. Can be served hot by adding cream to hot pureed mixture. Do not boil. Serves 8.
