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 moisture that cooks down into the sauce.
Vinegar
Adds sharp acidity that brightens the sauce and balances the sweetness.
Sugar
Adds sweetness that offsets the acidity of the vinegar and tomatoes.
Onions
Contribute savoury aroma and flavour as they soften during cooking.
Green peppers
Add a vegetal bitterness and extra bulk to the sauce.
Cinnamon
Adds warm aromatic spice that flavours the whole sauce.

The step that matters

Boil for 1.5 hours. A long, steady boil evaporates water and concentrates the sauce, so it thickens and the flavours deepen. Too short a boil leaves it thin and watery, and it may not keep well in jars.

Swap the onion

How well each one fits the dish's main ingredients (tomato, pepper, sugar, cinnamon, vinegar):

  1. Capsicumfits better
  2. Mustardfits better
  3. Cucumberfits better
  4. Onionthe original

Fit is the average pairing score against tomato, pepper, sugar, cinnamon, vinegar. Candidates are from the same food group and used in at least 100 recipes.
