Why it works: Clove and cinnamon 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 ↓
Grape Catsup

Directions
Squeeze grapes as for jelly, adding three-fourths pound of sugar to one pint of juice.
Spice to taste with salt, black pepper, nutmeg, cloves, and cinnamon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grape juice
- Forms the base of the ketchup and supplies most of its fruit flavor and moisture.
- Sugar
- Adds sweetness and body, and helps the mixture thicken as it cooks down.
- Vinegar
- Adds acidity and tang that balances the sweetness.
The step that matters
Boil until it is quite thick. As water evaporates, the sugar and fruit solids concentrate and can scorch on the bottom of the pan. Watching the heat and stirring helps the sauce thicken evenly without burning.
Swap the clove
How well each one fits the dish's main ingredients (sugar, vinegar, pepper, cinnamon):
- Allspicefits about as well
- Clovethe original
- Nutmegfits about as well
- Cardamomfits less well
Fit is the average pairing score against sugar, vinegar, pepper, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
