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 ↓
Rice Saute
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the rice
Boil the rice as in previous recipes.
Turn the cooked rice onto a hot platter and place it in a 400°F (200°C) oven to dry for 5 minutes, loosening the grains with a fork.
Set the dry rice aside to cool completely.
Fry and serve
In a frying pan, heat the butter and fry the onion slices until they begin to color.
Remove the onions and add the rice to the butter, one tablespoon at a time, to keep the grains separate.
Toss the rice lightly with a fork to keep the grains distinct, and as they color slightly, lift them with a perforated spoon into a heated colander.
Keep the colander in an open oven until all the rice is cooked, shaking gently to ensure it is free from grease.
Transfer the rice to a deep, uncovered dish.
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; drying and frying separate the grains so they stay distinct.
- Butter
- Fat that carries the frying, adding richness and helping the rice take on light browning.
- Onion
- Fried until it begins to color, adding sweetness and savory aroma to the rice.
The step that matters
Adding the rice to the butter. Adding the rice a tablespoon at a time and tossing it lightly keeps the grains from clumping together and absorbing too much fat. Cooled, dried grains fry more evenly and stay separate.

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