Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomato sauce
- Forms the liquid base and provides the sauce's main body and acidity.
- Butter
- Fat that softens and browns the onion, adding richness to the base.
- Ham or bacon
- Adds savory, smoky flavor that seasons the sauce as it simmers.
- Green pepper
- Adds fresh, slightly bitter vegetable flavor and soft texture after simmering.
- Red pepper
- Adds sweetness and color, softening as the sauce simmers.
The step that matters
Simmer for 30 minutes. Simmering lets the tomato sauce thicken and the flavors blend, while the peppers soften. Simmering too hard can scorch the sauce on the bottom of the pan.
