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

What each ingredient does

Butter
Browning in the pan adds a nutty, rich flavor to the base.
Tomatoes
Provide liquid and acidity that give the rice its sauce and tangy flavor.
Boiled rice
Forms the bulk of the dish and soaks up the tomato liquid.
Baking soda
Raises the pH slightly, which can deepen the color of the tomato mixture.
Sugar
Balances the acidity of the tomatoes with a touch of sweetness.

The step that matters

Mix well and let come to a boil again. Reheating the rice in the tomato liquid lets it absorb flavor and heat evenly. Brief boiling helps the baking soda react and the mixture thicken slightly, so it should be stirred to prevent scorching on the bottom of the pan.

Swap the tomato

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

  2. Potatofits better
  3. Sweet potatofits better
  4. Tomatothe original

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