Why it works: Tamarind and tomato match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 137 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Curried Oysters
Ingredients
Directions
Prepare the oysters
Open the oysters into a basin, keeping their liquor.
Make the curry base
In a saucepan, melt the butter over medium heat.
Add the sliced onion and fry until rich brown.
Stir in more butter and the curry powder, mixing well.
Gradually add hot water or broth, cover, and bring to a boil.
Add the grated cocoa-nut and sour tamarinds or chopped apple.
Simmer until the apple dissolves and the cocoa-nut is tender.
Mix in the thickening and salt, then boil for 5 minutes.
Finish and serve
Add the boiled vegetable marrow and tomatoes, if using.
Finally, stir in the oysters with their liquor and cocoa-nut milk.
Let the curry stew gently for a few minutes before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sea oysters
- Are the main protein, cooking gently in the sauce so they stay tender.
- Onion
- Browning the slices builds deep, sweet savoury flavour as the base of the curry.
- Curry powder
- Blooming it in butter releases its aromatic compounds into the fat, giving the curry its flavour.
- Cocoa-nut
- Simmered until tender, it adds body and richness to the sauce.
- Flour and water thickening
- Starch thickens the liquid into a smooth sauce that clings to the oysters and vegetables.
- Vegetable marrow
- Adds soft, mild bulk to the curry as it cooks down into the sauce.
The step that matters
Adding the oysters at the end. Oysters toughen and turn rubbery when overcooked. Stirring them in with their liquor near the end and letting the curry stew only gently keeps them tender and juicy.
Swap the tomato
The recipe marks tomato as optional. How well each one fits the dish's main ingredients (oyster, butter, onion, cocoa, tamarind, flour):
- Potatofits better
- Shallotfits better
- Okrafits better
- Tomatothe original
Fit is the average pairing score against oyster, butter, onion, cocoa, tamarind, flour. Candidates are from the same food group and used in at least 100 recipes.
