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 the seafood element of the curry.
- Butter
- Adds fat and richness to the base of the sauce.
- Onion
- Browning builds sweetness and savoury depth in the sauce.
- Flour
- Thickens the liquor into a smooth sauce when cooked with the butter.
- Oyster liquor
- Supplies the liquid and sea-salty flavour that forms the sauce.
The step that matters
Adding the flour and stirring until boiling. Flour mixed into melted butter must be cooked and stirred smoothly before liquid goes in, otherwise it forms lumps. Stirring until the liquid boils lets the starch swell and thicken the sauce fully.
Swap the onion
How well each one fits the dish's main ingredients (oyster, butter, flour, chicken):
- Shallotfits better
- Potatofits better
- Asparagusfits about as well
- Onionthe original
Fit is the average pairing score against oyster, butter, flour, chicken. Candidates are from the same food group and used in at least 100 recipes.
