Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the bulk, moisture and acidity that form the body of the sauce.
- Onions
- Add savory sweetness and aroma that build the sauce's base flavor.
- Vinegar
- Adds sharp acidity that preserves the sauce and balances its sweetness.
- Sugar
- Balances the acidity of the vinegar and tomatoes and aids browning as the sauce reduces.
- Green and red peppers
- Contribute vegetal flavor and bulk to the sauce's texture.
The step that matters
Boil for 2 hours, stirring occasionally. Long simmering reduces the liquid and softens the chopped vegetables into a thick sauce. Occasional stirring prevents sugars and solids from scorching on the bottom of the pot.
Swap the clove
How well each one fits the dish's main ingredients (tomato, pepper, onion, garlic, sugar, vinegar, celery):
- Cuminfits better
- Thymefits better
- Tarragonfits better
- Clovethe original
Fit is the average pairing score against tomato, pepper, onion, garlic, sugar, vinegar, celery. Candidates are from the same food group and used in at least 100 recipes.
