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

What each ingredient does

Sugar
Sweetens and thickens the syrup, and helps preserve the tomatoes.
Green tomatoes
Provide the bulk of the preserve, absorbing syrup as they cook.
Lemons
Add acidity that balances the sweetness and brightens the flavor.
Whole ginger
Adds a warm, aromatic spice flavor to the syrup.

The step that matters

Boiling the syrup until very thick. Sugar concentration is what preserves the fruit and sets the syrup. If the syrup is not boiled down enough, it stays thin and the preserve may spoil or fail to set.

Swap the tomato

  4. Tomatothe original

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