From Diane Seed's Mediterranean Dishes. Classic avgolemono ranks up there as one of the world's best soups.
- In a stock pot saute the leeks and celery in olive oil until softened. Add the chicken stock and simmer 20 minutes. Puree the mixture with an immersion blender.
- Just before serving, beat the lemon juice and eggs together until light and frothy. Slowly beat a ladleful of hot soup into the egg and lemon mixture, stir well, then whisk back into the soup pot.
- Stir the soup well to make sure the eggs are incorporated so that they do not curdle.
- Adjust seasoning, add salt and pepper and serve warm. Garnish each serving with fresh dill if desired.
