  2. Add the salt, spices, and vinegar to the chopped ingredients.

Cook and store

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 liquid that cooks down into the sauce body.
Onions
Add savory depth and aroma as they soften during the long cook.
Vinegar
Adds acidity that gives the sauce its sharp tang and helps preserve it.
Brown sugar
Adds sweetness and helps the sauce thicken and turn dark as it cooks.
Peppers
Supply heat and vegetable flavour to the sauce.

The step that matters

Stirring during the long cook. The sauce is cooked for about 3 hours and is thick and sugary, so it can scorch on the bottom of the pot. Frequent stirring prevents burning and gives an even texture.

Swap the onion

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

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

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