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 the sauce
In a saucepan, melt the butter and cook the sliced onion until golden.
In the butter, mix the flour, curry powder, and salt.
Drain the oysters and boil the oyster liquor, skimming it. 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.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they 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 ingredient; browning on the griddle adds savory flavor and texture.
- Flour
- Thickens the butter and curry mixture so the sauce becomes body-rich rather than watery.
- Onion
- Softens and sweetens as it turns golden, forming the base flavor of the sauce.
- Curry powder
- Supplies the spiced aroma that defines the dish, bloomed briefly in the hot butter.
- Butter
- Carries the onion and spices and adds rich fat flavor to the sauce.
The step that matters
Browning the oysters on the griddle. Oysters overcook quickly and turn rubbery, so cooking them a few at a time in a hot pan keeps them tender and gives browned surfaces through the Maillard reaction.
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.
