Why it works: Sugar and vinegar are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 20,806 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and clove barely smell alike, yet cooks put them together in 17,182 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gooseberries
- Provide the main fruit body and natural pectin that thickens the ketchup as it cooks.
- Brown sugar
- Adds sweetness and bulk, and helps thicken the mixture as it reduces.
- Vinegar
- Adds acidity that balances the sweetness and helps preserve the ketchup.
- Cloves
- Contribute a warm, aromatic spice flavour to the ketchup.
The step that matters
Adjust the vinegar to taste, then bottle immediately. Vinegar is added near the end, after the sugar has concentrated the mixture. Tasting before bottling lets the cook balance sweetness and sharpness, and bottling while hot helps the ketchup keep well.
Swap the clove
How well each one fits the dish's main ingredients (sugar, vinegar):
- Cinnamonfits better
- Tarragonfits better
- Peppermintfits better
- Clovethe original
Fit is the average pairing score against sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
