Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the bulk and the main body of the sauce as they break down.
- Onions
- Add savoury depth and body as they soften during the long stew.
- Vinegar
- Adds acidity that preserves the sauce and gives it a sharp tang.
- Sugar
- Adds sweetness that balances the acidity of the vinegar.
- White mustard
- Adds sharp, pungent flavour to the finished sauce.
The step that matters
Stew the mixture slowly for 2 to 3 hours. Slow, gentle cooking lets the tomatoes and onions break down and thicken into a smooth sauce while the vinegar's sharpness mellows. Rapid boiling can scorch the sugar and leave the sauce uneven.

Fit is the average pairing score against tomato, vinegar, mustard, ginger, clove, allspice, sugar. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
