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 cook down into the sauce.
Onions
Add savory bulk and body to the sauce as they soften.
Brown sugar
Adds sweetness that balances the sharpness of the vinegar.
Vinegar
Adds acidity that brightens the sauce and balances its sweetness.
Ginger
Contributes a warm, aromatic flavor to the sauce.

The step that matters

Simmer until thickened. Simmering lets water evaporate from the tomatoes and onions, so the sauce thickens. If it is not cooked long enough, it stays thin and watery.

Swap the onion

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

  1. Capsicumfits better
  2. Sweet potatofits better
