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 and acidity that give the sauce its base.
- Sugar
- Adds sweetness and helps thicken the sauce as it reduces.
- Vinegar
- Adds acidity that sharpens flavour and helps preserve the sauce.
- Celery
- Contributes bulk and its distinctive savoury, herbal flavour.
- Onions
- Add savoury depth and aroma as they soften during boiling.
- Pickles
- Contribute tangy, briny flavour that complements the vinegar.
The step that matters
Boil until thick. Sugar and vinegar concentrate as water evaporates, so the sauce thickens gradually. Stopping too early leaves it thin and watery, while over-reducing can scorch the sugar.
Swap the onion
How well each one fits the dish's main ingredients (tomato, pepper, celery, sugar, vinegar):
- Capsicumfits better
- Mustardfits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against tomato, pepper, celery, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
