Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness and helps the onions brown in the pan.
- Onion
- Browning in the fat builds sweet, savoury flavour.
- Rice
- Forms the bulk of the dish and carries the other ingredients.
- Red kidney beans
- Add body, texture and substance to the dish.
- Sour cream
- Adds moisture and a tangy, creamy texture.
- Asiago cheese
- Melts to bind the mixture and add savoury flavour.
The step that matters
Cook the onions until they begin to brown. Browning onions in butter caramelises their natural sugars, building sweet, savoury depth. Stopping too early leaves a flat, raw onion taste, while over-browning can turn them bitter.

Fit is the average pairing score against butter, onion, rice, chicken, cream, cheese, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
