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 as they break down.
- Onions
- Add sweetness and savory depth as they soften during the long cook.
- Butter
- Adds fat for a rounder, silkier mouthfeel and carries aroma.
The step that matters
Cook over medium heat, stirring occasionally. Tomatoes and onions with butter can scorch or stick to the base of the pan. Occasional stirring spreads heat evenly, while gentle simmering softens the vegetables and concentrates flavor over the full 45 minutes.

Fit is the average pairing score against tomato, onion, parsley, thyme, butter. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
