Make the sauce

  1. In a saucepan, combine the oysters with butter and the reserved oyster liquor.

Butter and flour share little aroma chemistry, yet 124,287 recipes mention both: they likely work on texture and structure more than aroma.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Oysters
Provide the main flavour and body of the sauce.
Butter
Adds richness and a smooth, rounded mouthfeel to the sauce.
Flour
Thickens the sauce by absorbing liquid and swelling when heated.
Lemon juice
Adds acidity that brightens the savoury oyster flavour.
Catsup
Contributes sweetness and tang that rounds out the seasoning.

The step that matters

Heat gently until warmed through. Flour-thickened sauces can curdle, turn grainy, or break if boiled hard. Gentle heat lets the starch thicken smoothly and keeps the butter emulsified and the oysters tender rather than rubbery.
