Why it works: Clove and allspice match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 7,874 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Barberry Catsup
Ingredients
Directions
Prepare the fruit
Stew barberries with water until well cooked, then strain through a sieve.
In a separate saucepan, stew cranberries, raisins, quince, onions, and water for 30 minutes, then pass through a sieve.
Make the ketchup
Mix the barberry juice with the cranberry mixture.
Add vinegar, salt, brown sugar, cloves, allspice, black pepper, celery seed, cayenne, cinnamon, ginger, and nutmeg.
Let the mixture boil for one minute. If too thick, add vinegar or water.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barberries
- Provide the tart base flavor and much of the body of the ketchup.
- Cranberries
- Add acidity and pectin that help the ketchup thicken as it cooks.
- Quince
- Adds natural pectin and a fragrant, tart note that supports setting.
- Brown sugar
- Adds sweetness and depth, and helps balance the sharp fruit acidity.
- Vinegar
- Adds acidity for sharpness and helps preserve the sauce.
The step that matters
Boiling and adjusting thickness. The ketchup thickens as it reduces and boils, so judging consistency matters. Adding vinegar or water at the end changes both flavor and texture, so add gradually and recheck after boiling.
