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 tangy flavour of the sauce.
Brown vinegar
Adds acidity that sharpens flavour and helps preserve the sauce.
White sugar
Adds sweetness that balances the acidity and spices.
Garlic
Adds pungent aroma and savoury depth to the sauce.
Ground cloves
Contribute warm, aromatic spice notes that define the sauce's flavour.
Ground allspice
Adds warm, aromatic spice notes that round out the sauce.

The step that matters

Boil until smooth and no watery particles remain. The long reduction evaporates excess water and concentrates the tomato, so the sauce thickens and keeps its flavour. Stopping early leaves a thin, watery sauce that is more likely to spoil in the bottle.

Swap the tomato

How well each one fits the dish's main ingredients (vinegar, clove, allspice, sugar, garlic, pepper):

  1. Mustardfits better
  2. Capsicumfits better
