Why it works: Rice and onion 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 ↓
Baked Rice Curry
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Wash the rice in three waters and soak it in enough water to cover for 15 minutes.
Boil the onion in a quart of water with salt until very soft.
Strain the water, squeezing the onion in a cloth to extract all the liquid.
Add the curry powder to the strained water and bring it to a boil.
Pour the boiling curry water over the soaked rice.
Bake and serve
Transfer everything to a covered casserole dish and bake in a 350°F (175°C) oven until the rice absorbs the liquid and is soft but not broken.
Serve in a deep dish and drizzle with melted butter, gently loosening the rice with a fork.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raw rice
- Forms the bulk of the dish and absorbs the curry-flavoured liquid as it bakes.
- Onion
- Its cooked juice adds savoury sweetness and body to the curry water.
- Curry powder
- Adds the spiced aroma and colour that flavour the absorbed liquid.
- Melted butter
- Adds richness and a glossy finish to the rice when drizzled on top.
The step that matters
Baking until the rice is soft but not broken. Rice must absorb the liquid slowly inside a covered dish. Too much heat or stirring can break the grains and make them mushy, while underbaking leaves them firm at the centre.

- Onionthe original
Fit is the average pairing score against rice, butter. Candidates are from the same food group and used in at least 100 recipes.
