Why it works: Onion and rice are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 10,433 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Curry of Oysters
Ingredients
Directions
Prepare
Melt the butter in a saucepan and cook the sliced onion until golden.
Drain the oysters and boil the liquor, skimming it.
Make the sauce
In the butter, mix the flour, curry powder, and salt.
Add the oyster liquor, stirring until boiling.
Cook and serve
Heat a griddle and cook the oysters a few at a time until browned on both sides.
Transfer the cooked oysters to the sauce and serve hot over a border of plain boiled rice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main protein and savoury flavour of the dish.
- Flour
- Thickens the butter and curry mixture into a sauce.
- Curry powder
- Adds the spiced, aromatic flavour that defines the dish.
- Onion
- Adds sweetness and savoury depth as it turns golden in the butter.
- Butter
- Carries the spices and onion and adds richness to the sauce.
The step that matters
Browning the oysters on the griddle. Oysters cook quickly and turn rubbery if overcooked. Browning them briefly in small batches gives colour and flavour without drying them out, and crowding the griddle would steam them instead of browning.
Swap the onion
How well each one fits the dish's main ingredients (butter, oyster, flour, rice):
- Shallotfits better
- Cucumberfits better
- Okrafits better
- Onionthe original
Fit is the average pairing score against butter, oyster, flour, rice. Candidates are from the same food group and used in at least 100 recipes.
