Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Green tomatoes
Provide the bulk of the sauce and, once salted and drained, a firm texture that holds up to long simmering.
Coarse sea salt
Draws water out of the sliced tomatoes, firming them and concentrating their flavour.
Onions
Add sweetness and body that soften into the sauce during simmering.
Vinegar
Adds acidity that sharpens the flavour and helps preserve the finished sauce.
Mustard seed
Adds pungent, sharp flavour that mellows during the long simmer.

The step that matters

Simmer until the tomatoes look clear. Simmering long enough softens the tomato slices and lets the spices and vinegar blend into the sauce. Stopping early leaves the texture firm and the flavour harsh and unintegrated.

  3. Shallotbetter flavor fit
  4. Onionthe original

Fit is the average pairing score against tomato, mustard, clove, pepper, ginger, allspice, 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).
