Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that fries the onion, adding richness and browning flavour.
- Onion
- Softens and browns in butter, adding sweetness and savoury depth to the rice.
- Tomato pulp
- Adds acidity, moisture and tomato flavour that colours the rice.
- Boiled rice
- Forms the bulk of the dish and absorbs the butter and tomato flavours.
The step that matters
Frying the onion until light brown. Frying onion in butter until it turns golden develops sweet, savoury flavour through browning. Stopping too early leaves it raw-tasting, while over-browning makes it bitter.
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.
