Add the chopped tomatoes, carrots, onion, celery, turnip, bouquet garni, egg whites, crushed egg shells, and plenty of seasoning.
Bring almost to the boiling point, whisking all the time with a flat whisk.

Carefully pour the soup through a scalded fine cloth such as muslin, keeping the froth back.
Repeat if necessary until the liquid is clear.
