Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide most of the liquid and body, which reduces as the sauce thickens.
- Celery
- Adds its savory, herbal aroma to the sauce.
- Onions
- Build savory depth and aroma as they soften into the sauce.
- Sugar
- Adds sweetness and balances the sharpness of the vinegar.
- Vinegar
- Adds acidity that brightens the sauce and balances its sweetness.
- Red peppers
- Add sweetness and a mild, fresh flavor to the sauce.
The step that matters
Stirring while the sauce thickens. Sugar and tomato solids settle and scorch on the bottom of the pot when heated for a long time. Occasional stirring over medium heat keeps the mixture from sticking and burning, which would give a bitter taste.
Swap the onion
How well each one fits the dish's main ingredients (tomato, celery, pepper, sugar, vinegar):
