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 ↓
An Indian Curry
Ingredients
Directions
Make the sauce
Melt the butter in an iron saucepan.
Fry the onion and apple in the butter for five minutes, stirring occasionally.
Mix the curry powder and rice flour with the milk from the cocoa-nut and lemon juice.
Add the stock.
Pour this mixture into the saucepan and stir until boiling.
Simmer and serve
Add the grated cocoa-nut and chutney with the meat.
Let the mixture simmer gently for fifteen minutes.
Just before serving, add the cream and a little salt.
Serve on a hot dish with rice around it or separately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice flour
- Thickens the sauce so it clings to the meat and rice.
- Apple
- Softens into the onion base, adding gentle sweetness to balance the curry spices.
- Butter
- Carries the onion and apple flavour and adds richness to the sauce.
- Lemon juice
- Adds acidity that brightens the sauce and balances the sweetness of the apple and cocoa-nut.
- Cocoa-nut
- Contributes coconut milk and grated flesh for body, moisture and a mellow sweetness.
- Cream
- Adds richness and a smooth, velvety texture when stirred in at the end.
The step that matters
Pouring the flour mixture into the boiling stock. Rice flour thickens only when heated, and adding it to liquid without first mixing it smoothly with cold liquid can leave lumps. Stirring until the sauce boils lets the starch swell evenly into a smooth sauce.
