What each ingredient does

Fowls: Form the main body of the dish, becoming tender as they simmer slowly in water.
Butter: Adds richness and a smooth fat to the serving sauce, softening the lean poultry.

Swap the celery

The recipe marks celery as optional. How well each one fits the dish's main ingredients (flour, parsley, butter, oyster, sauce):
