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.
