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 provides its main starchy structure.
Butter
Adds fat that carries flavor and helps the rice brown in the pan.
Tomatoes
Add moisture and a mild acidity that brightens the savory rice.
Grated cheese
Adds savory, salty flavor and melts slightly into the rice.

The step that matters

Fry the rice in butter until browned. Rice needs enough fat and direct contact with the hot pan so its surface dries and browns, which builds toasty flavor. Crowding the pan or stopping too early leaves it soft and pale.

Swap the tomato

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

  1. Capsicumfits about as well
  2. Potatofits about as well
  3. Tomatothe original
  4. Asparagusfits about as well

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