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 and flesh of the preserve, which softens and absorbs the spiced syrup.
- Brown sugar
- Sweetens the dish and, when boiled down, thickens the syrup into a rich, glossy coating.
- Vinegar
- Adds acidity that balances the sweetness and helps keep the tomatoes tangy.
- Cloves
- Contribute warm, aromatic spice flavour to the syrup.
- Allspice berries
- Contribute warm, aromatic spice flavour that blends with the cloves in the syrup.
The step that matters
Boil the syrup until thick. Sugar syrup thickens as water evaporates and its concentration rises. Stopping too early leaves it thin, while overcooking can make it sticky and dark, so the syrup must be watched as it reduces.
Swap the tomato
How well each one fits the dish's main ingredients (sugar, vinegar, clove, allspice):
- Mustardfits better
- Capsicumfits better
- Horseradishfits better
- Tomatothe original
Fit is the average pairing score against sugar, vinegar, clove, allspice. Candidates are from the same food group and used in at least 100 recipes.
