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, flavor, and liquid that forms the ketchup.
Coarse sea salt
Draws moisture out of the tomatoes and seasons them during the 24-hour rest.
Wine
Adds acidity and a tangy depth of flavor to the finished sauce.
Cloves
Contribute warm, aromatic spice flavor to the sauce.
Black pepper
Adds sharp, pungent spice that balances the sweetness of the tomatoes.
Nutmegs
Add warm, aromatic spice notes to the sauce.

The step that matters

Boiling the mixture for 30 minutes. Long simmering thickens the sauce by evaporating water and concentrates the flavors. Boiling too briefly leaves it thin and the spices raw-tasting.

Swap the tomato

How well each one fits the dish's main ingredients (clove, pepper, nutmeg, wine):

  1. Capsicumfits better
  2. Carrotfits better
