Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ripe tomatoes
- Provide the main body of the preserve and soften into the syrup as they stew.
- Brown sugar
- Sweetens the dish and thickens the syrup as it boils down, adding color and depth.
- Cider vinegar
- Adds acidity that balances the sweetness and helps preserve the tomatoes.
The step that matters
Boil the syrup until thick like molasses. Sugar concentrates as water evaporates, so the syrup thickens. Stopping too early leaves a thin liquid that can separate from the tomatoes, while overcooking can turn it hard or scorch the sugar.
Swap the tomato
How well each one fits the dish's main ingredients (sugar, cider, vinegar, clove, allspice):
- Mustardfits better
- Capsicumfits better
- Horseradishfits better
- Tomatothe original
Fit is the average pairing score against sugar, cider, vinegar, clove, allspice. Candidates are from the same food group and used in at least 100 recipes.
