What each ingredient does

Oysters
Provide the main flavor and tender texture of the dish.
Flour
Thickens the liquid into a smooth, creamy sauce as it heats.
Milk
Adds moisture and richness, softening the sauce into a creamy base.

The step that matters

Drop in the oysters and remove from heat once it boils again.. Oysters toughen and shrink when overcooked, so they should be heated just until the liquid returns to a boil and then removed promptly to stay tender.
