Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Form the bulk of the sauce and provide its body and flavour when boiled down.
- Sugar
- Adds sweetness that balances the sharp vinegar and salt.
- Vinegar
- Adds acidity that preserves the sauce and gives it its sharp tang.
- Onions
- Add savoury flavour and aroma to the sauce base.
- Celery seed
- Supplies the characteristic celery flavour of the sauce.
The step that matters
Stirring in the vinegar just before removing from heat. Vinegar is added late so its sharp acidity and volatile aroma are not cooked off during prolonged boiling, keeping the sauce tangy.
Swap the white pepper
How well each one fits the dish's main ingredients (tomato, pepper, onion, sugar, vinegar, celery, clove):
- Thymefits better
- Tarragonfits better
- Allspicefits better
- White pepperthe original
