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 ↓
Rice Pilaw
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Melt the butter in a saucepan.
Add the chopped onion and cook for a few minutes without browning.
Stir in the rice and heat until hot.
Pour in the hot bouillon, cover the saucepan, and cook in a 350°F (175°C) oven for 18 minutes.
If no oven is available, cook gently on the stove, covered, without stirring.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rice
- Forms the bulk of the dish and absorbs the bouillon as it cooks, becoming tender.
- Butter
- Adds fat and richness, coating the rice grains so they stay separate.
- Onion
- Adds aromatic flavour as it softens in the butter before the rice goes in.
- White bouillon
- Supplies the cooking liquid that the rice absorbs, seasoning it as it cooks.
The step that matters
Cooking the rice covered without stirring. Stirring releases starch from the rice grains, which makes the pilaf sticky. Keeping the pan covered traps steam so the liquid is absorbed evenly and the grains stay separate.
Swap the onion

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