Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Lard
Fat that carries flavor and helps the rice brown in the pan.
Rice
Forms the body of the dish and absorbs the tomato liquid as it cooks.
Tomatoes
Provide moisture, acidity, and color that build the sauce as they simmer.

The step that matters

Browning the rice in the lard. Frying the rice until golden lets its starches caramelize and the Maillard reaction add toasty, nutty flavor. Rice added to the tomatoes while still pale tastes flatter and less rich.

Swap the tomato

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

  1. Capsicumfits better
  2. Carrotfits about as well
  3. Tomatothe original
  4. Spinachfits about as well

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