Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ripe tomatoes
- Provide the main body, moisture and sweetness of the sauce once cooked down.
- Vinegar
- Adds acidity that sharpens flavour and helps preserve the sauce during long simmering.
- White mustard seed
- Adds pungent, sharp flavour that mellows during the long simmer.
- Red pepper pods
- Add heat and a sweet, peppery aroma to the cooked tomato base.
The step that matters
Simmer slowly for 3 to 4 hours. Long, gentle simmering evaporates water and concentrates the sauce, while mellowing sharp notes from the vinegar and mustard. Too fast a boil can scorch the sugars in the tomatoes and leave the sauce thin or bitter.

Fit is the average pairing score against tomato, pepper, mustard, vinegar. 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).
