CRAIG CLAIBORNE'S SORREL SOUP

Steps:

• Pick over the sorrel. Remove and discard any tough stems and blemished leaves. Rinse and pat dry. Pack the leaves closely and cut them crosswise into thin strips. Set aside.
• Heat the butter in a saucepan and add the leeks. Cook, stirring, until wilted. Do not brown.
• Add the potatoes to the saucepan and pour in the broth. Bring to the boil and simmer 10 to 15 minutes or until the potatoes are tender.
• Strain the broth. Transfer the solids to the container of a food processor. Add about one cup of the cooking liquid and blend thoroughly. Pour the mixture into a mixing bowl and add the remaining liquid. Chill thoroughly.
• Add the sorrel to the chilled soup. Add salt and pepper to taste. Stir in the cream and refrigerate until ready to use.
