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 ↓
Tokato Catsup
Ingredients
Directions
Prepare the tomatoes
Wash the tomatoes and slice them.
Place the sliced tomatoes in a large pot and let them stew gently until soft, without stirring.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body, juice and tomato flavor of the ketchup.
- Vinegar
- Adds acidity that gives the ketchup its tang and helps keep it stable.
- Cloves
- Contribute warm, aromatic spice flavor to the finished sauce.
- Allspice
- Adds warm, aromatic spice flavor that deepens the sauce.
- Mace
- Adds a delicate, warm aroma to the spiced sauce.
The step that matters
Reducing the juice until the volume is halved. Cooking down the juice concentrates its flavor and thickens it, and evaporating water is what gives the sauce its body. Stopping too early leaves it thin and watery, while reducing too far can make it overly thick or scorched on the bottom of the pot.
Swap the mace
How well each one fits the dish's main ingredients (tomato, clove, allspice, pepper, vinegar):
- Thymefits better
- Cinnamonfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against tomato, clove, allspice, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
