Take six stalks of celery well washed. Make a stock of one soup hen or
chicken bones, and five pounds of veal bones in the usual manner, with
carrots, onions, parsley, bay leaves, salt and pepper. Place the celery
in a vessel and strain the broth over it. Boil until soft and let cool
off in its own broth.
When cold press the broth out of the celery with the hand, gently, and
place on a plate. Season with salt, fresh ground black pepper, chervil,
and one-quarter white wine vinegar with tarragon to three-quarters of
best olive oil.
