Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Softens and sweetens when fried, building a savoury aroma for the rice.
- Butter
- Carries flavour and gives the onion a light golden browning.
- Boiled rice
- Forms the bulk of the dish and soaks up the butter and tomato flavour.
- Tomato pulp
- Adds moisture, acidity and colour to the rice.
The step that matters
Frying the onion until light brown. The onion's natural sugars caramelise gently as it browns, giving sweet, savoury depth. Browning past light brown turns bitter, so the onion should be watched closely.
Swap the onion
How well each one fits the dish's main ingredients (butter, rice, pepper, tomato, cheese):
- Capsicumfits better
- Potatofits better
- Asparagusfits about as well
- Onionthe original
Fit is the average pairing score against butter, rice, pepper, tomato, cheese. Candidates are from the same food group and used in at least 100 recipes.
