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
