Why it works: Cinnamon and clove match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,189 recipes. Both carry ethyl cinnamate, which smells sweet, balsamic. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grapes
- Provide the main body, pulp and flavour of the ketchup.
- Sugar
- Adds sweetness and helps preserve the ketchup.
- Sharp vinegar or wine
- Adds acidity and thins the ketchup to the desired consistency.
The step that matters
Thin to the proper consistency. Sugar and cooked fruit thicken as they cool, so the liquid should be adjusted by eye rather than fixed in advance. Adding too much vinegar or wine makes the ketchup thin and sharp, while too little leaves it thick.
Swap the mace
How well each one fits the dish's main ingredients (grape, cinnamon, clove, sugar, vinegar):
- Allspicefits better
- Nutmegfits better
- Cardamomfits better
- Macethe original
Fit is the average pairing score against grape, cinnamon, clove, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
