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.
