3⁄4 cup coarsely chopped peeled and seeded cucumber
2 tablespoons dry sherry
1⁄4 cup coarsely chopped scallions, with some of the green stems
2 cups mild flavored chicken stock
1 teaspoon salt
hot pepper sauce (optional)
plain yogurt or light cream, to garnish
Directions
Cut the avocados in half, remove the pits, and peel. Coarsely chop the flesh and place in a food processor or blender. Add the lemon juice and process until very smooth.
Add the cucumber, sherry, and most of the scallions, reserving a few for the garnish. Process again until smooth.
In a large bowl, combine the avocado mixture with the chicken stock. Whisk until well blended. Season with the salt and a few drops of hot-pepper sauce, if liked. Cover the bowl and place in the refrigerator to chill thoroughly.
To serve, fill individual bowls with the soup. Place a spoonful of yogurt or cream in the center of each bowl and swirl with a spoon. Sprinkle with the reserved chopped scallions.
