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.
Soak the rice in enough water to cover for 15 minutes.
Make the curry water
Boil the onion in a quart of water with the salt until very soft.
Strain the water.
Squeeze the onion in a cloth.
Discard the onion.
Add the curry powder to the strained water and bring it to a boil.
Bake and serve
Pour the boiling water over the soaked rice.
Transfer everything to a covered casserole dish.
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.
Pour melted butter over it.
Loosen the rice gently 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, softening and absorbing the curried liquid as it bakes.
- Curry powder
- Gives the rice its spiced aroma and yellow colour as it is stirred into the hot water.
- Onion
- Is boiled until very soft, adding savoury flavour to the cooking water before being discarded.
- Melted butter
- Adds fat and richness, coating the grains and carrying flavour when poured over the served rice.
The step that matters
Bake until the liquid is absorbed but the rice is not broken. Rice grains absorb liquid as starch gelatinises during baking. Too much heat or stirring can break the grains and make them mushy, so check for tenderness without over-handling.
Swap the onion
How well each one fits the dish's main ingredients (rice, butter):
- Potatofits 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.
