The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Small red or yellow tomatoes
Provide the fruit that is preserved, holding its shape when boiled gently in syrup.
Sugar
Sweetens the fruit and, as a thick syrup, helps preserve it.
Lemon
Adds acidity that brightens the flavour and balances the sweetness.
Egg white
Clarifies the syrup: as it boils it collects impurities that are then skimmed off.
Ginger root
Adds a warm, aromatic flavour to the syrup.

The step that matters

Boil the tomatoes slowly. A gentle simmer keeps the skins intact and the fruit firm. A hard boil breaks the skins and softens the flesh, while slow heat lets the syrup penetrate gradually.

Swap the tomato

How well each one fits the dish's main ingredients (lemon, sugar, ginger, egg):

  1. Sweet potatofits better
  2. Arrowrootfits better
  3. Shallotfits better
  4. Tomatothe original

Fit is the average pairing score against lemon, sugar, ginger, egg. Candidates are from the same food group and used in at least 100 recipes.
