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

What each ingredient does

Tomatoes
Form the bulk of the preserve and provide the base flavour and body.
Sugar
Sweetens the preserve and thickens it as the water cooks off.
Vinegar
Adds acidity that balances the sweetness and sharpens the spice flavour.
Cloves
Contribute a warm, aromatic spice flavour.
Mixed spices
Add aromatic warmth that rounds out the flavour of the preserve.

The step that matters

Adding the vinegar and spices after the first two hours. Sugar and tomato need time to cook down and thicken before the acid and spices go in. Adding them too early can leave the tomato less concentrated and the spice flavour harsh, while the long boil afterward lets everything blend.

Swap the tomato
