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

What each ingredient does

Tomatoes
Provide the main body, moisture, and bright acidity of the sauce.
Onion
Adds savory sweetness and aromatic depth as the cooked base flavor.

The step that matters

Cooking over medium heat while stirring. Tomatoes release liquid as they cook, and their sugars can scorch on the pot bottom if not stirred. Stirring keeps the sauce from burning and helps it soften evenly enough to mash through a colander.

Swap the clove

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

  1. Garlicfits better
  2. Thymefits better
  3. Cuminfits better
  4. Clovethe original

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