Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the bulk of the dish and its fresh, tart body as they cook down.
- White sugar
- Adds sweetness and helps thicken the mixture as it cooks down into a preserve.
- Vinegar
- Adds acidity that balances the sweetness and gives the preserve its tangy flavor.
The step that matters
Boil slowly until the mixture thickens slightly. Sugar and acid concentrate as water evaporates, so a gentle boil lets the mixture thicken without scorching on the bottom of the pot. Stir often to keep it from sticking.
Swap the tomato
How well each one fits the dish's main ingredients (sugar, vinegar):
- Mustardfits better
- Capsicumfits better

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