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 a little 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, drizzling with melted butter and gently fluffing 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 curried liquid as it bakes, becoming soft.
- Onion
- Boiled until very soft, its flavour and body are carried into the strained cooking liquid.
- Curry powder
- Adds aroma and warm spice flavour to the cooking water that the rice absorbs.
- Butter
- Melted over the finished rice to add richness and fat for flavour.
The step that matters
Baking until the rice is soft but not broken. Rice must absorb the liquid slowly under cover; too much heat or stirring can break the grains and leave them mushy or unevenly cooked, while too little time leaves them firm at the centre.
Swap the onion
How well each one fits the dish's main ingredients (rice, butter):
- Potatofits better
- Asparagusfits better
- Leekfits about as well
- 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.
