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

What each ingredient does

Stewed tomatoes
Provide the main body and acidity, with baking soda neutralizing some of that acid.
Baking soda
Reacts with the tomatoes' acid, releasing gas that foams until it is spent.
Milk
Forms the creamy base that the cornstarch thickens.
Cornstarch
Thickens the milk as it heats, giving the dish a smooth, body-rich texture.
Butter
Adds richness and a smooth mouthfeel to the milk base.

The step that matters

Thicken milk with cornstarch. Cornstarch must be fully dispersed and heated to thicken; added lumpy or undercooked, it leaves a pasty texture and raw starch taste. Keep stirring while it heats.

Swap the white pepper

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

  1. Thymefits better
  2. Parsleyfits better
  3. Cinnamonfits better
  4. White pepperthe original

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