1 very ripe medium avocado
3 cups cold chicken stock, fat skimmed off
1 cup sour cream, divided
Salt and freshly ground black pepper to taste
Pinch of cayenne pepper or a few drops Tabasco
2 tablespoons finely minced chives, divided
1 cooked boneless chicken breast
1 tablespoon minced green or red chiles, or 2 tablespoons roasted red bell
pepper or pimiento (garnish, optional)
Using stainless-steel knife, peel and pit avocado and cut into chunks. Puree in food processor or by rubbing through sieve with wooden spoon. Blend in chicken stock using blender, food processor or wire whisk. Beat in 2/3 cup sour cream until smooth and frothy. Season with salt and peppers or Tabasco and 1 tablespoon chives. Place in refrigerator to chill and thicken for 2 to 3 hours. (Can be made to this point up to 24 hours in advance; cover tightly with plastic wrap.)
About 30 minutes before serving, place 4 soup cups or bowls in refrigerator to chill. Let chicken stand at room temperature (no more than 30 minutes). Cut chicken in fine dice or shred. Using fork, beat remaining 1/3 cup sour cream until thin. Place chicken in chilled cups. Ladle bisque over it. Drizzle beaten sour cream over it and garnish with remaining 1 tablespoon chives, minced chiles, roasted red pepper or pimiento, if desired. Serve cold.
