Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the bulk, acidity and body that form the base of the sauce.
- Onions
- Add savoury sweetness and aromatic depth as they soften during the long boil.
- Celery
- Contributes a fresh, vegetal aroma and savoury flavour to the sauce.
- Sugar
- Adds sweetness that balances the acidity of the vinegar and tomatoes.
- Vinegar
- Adds acidity that sharpens flavour and helps preserve the sauce.
The step that matters
Boil the mixture for 1.5 hours. A long, steady boil reduces the water in the pot and softens the vegetables, thickening the sauce. Too little cooking leaves it thin and raw-tasting. Stir to keep solids from scorching on the bottom of the pot.
Swap the onion
