What each ingredient does

Milk
Forms the liquid base of the soup, giving it body and a creamy texture.
Oysters
Provide the main flavour and briny taste of the soup.
Flour
Thickens the broth slightly, giving it body.
Butter
Adds richness and fat, rounding out the flavour and mouthfeel.

The step that matters

Adding the oysters. Oysters toughen and turn rubbery if overcooked, so they should be added last and cooked only briefly until their edges curl. Keeping the soup below a hard boil at this point preserves their tender texture.
