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 and absorbs the water and juices as it cooks.
Bacon grease
Fat that carries flavor and helps the vegetables brown in the pan.
Tomatoes
Provide liquid and acidity that flavor the rice as it simmers.
Onion
Adds savory sweetness and aroma as it fries.
Green peppers
Add a fresh, slightly bitter vegetable flavor and some texture.

The step that matters

Fry the mixture until nearly brown. Browning the onion, pepper and tomato concentrates their sugars through the Maillard reaction and caramelization, building deeper flavor. Stopping too early leaves the dish tasting flat and raw.

Swap the onion

How well each one fits the dish's main ingredients (rice, tomato, pepper):

  1. Capsicumfits better
  2. Okrafits better
  3. Carrotfits better
  4. Onionthe original

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