Why it works: Pepper and clove match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 17,451 recipes. Both carry ethyl octanoate, which smells fruity, wine. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cherries
- Provide the main fruit body and natural sweetness that forms the bulk of the ketchup.
- Brown sugar
- Adds sweetness and helps thicken the mixture as it cooks down into a glossy sauce.
- Vinegar
- Adds acidity that balances the sweetness and helps preserve the ketchup.
The step that matters
Cooking the mixture down for 2 hours. Long, gentle simmering lets water evaporate so the sauce thickens. Stirring prevents the sugars from scorching on the bottom of the pot.
Swap the clove
How well each one fits the dish's main ingredients (sugar, vinegar, pepper):
- Cinnamonfits about as well
- Tarragonfits about as well
- Allspicefits about as well
- Clovethe original
Fit is the average pairing score against sugar, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
