The flavor team

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.

  1. Lemon + gingertop 5% of all pairs

    Shared aroma: beta-phellandrene (minty, terpene).

    Shared aroma: 1-penten-3-one (fish, pungent).

Sugar and ginger barely smell alike, yet cooks put them together in 14,054 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Green tomatoes
Form the bulk of the preserve and carry the fruit texture once cooked clear.
Sugar
Sweetens the preserve and, boiled into syrup, thickens it and helps preserve the fruit.
Lemon juice
Adds acidity that balances the sweetness and brightens the flavor.
Ginger and mace mixture
Adds warm, aromatic spice flavor to the syrup and fruit.

The step that matters

Boil the syrup until thick. Sugar concentration drives both set and preservation. Syrup that is not boiled down enough stays thin, so the fruit can ferment or spoil in storage.

Swap the mace

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

  1. Cardamomfits better
  2. Corianderfits better
  3. Cinnamonfits better
  4. Macethe original

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