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 flavor that cook down into the sauce.
- Olive oil
- Adds fat that carries aroma and gives the sauce a smoother mouthfeel.
- Onion
- Adds savory sweetness and aromatic base flavor as it softens.
- Garlic
- Contributes pungent aroma that mellows and deepens during cooking.
- Celery
- Adds subtle savory, vegetal flavor to the aromatic base.
The step that matters
Stir occasionally until the juice thickens. Tomatoes release a lot of water, and cooking slowly over medium heat lets it evaporate so the sauce thickens. Stirring prevents scorching on the bottom of the pot.
Swap the clove
How well each one fits the dish's main ingredients (onion, garlic, celery, parsley, olive, pepper, tomato):
- Thymefits better
- Cuminfits better
- Basilfits better
- Clovethe original
Fit is the average pairing score against onion, garlic, celery, parsley, olive, pepper, tomato. Candidates are from the same food group and used in at least 100 recipes.
