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, pulp and flavor base of the ketchup.
Brown sugar
Adds sweetness and rich flavor that balances the vinegar's sharpness.
Vinegar
Adds sharp acidity that brightens the flavor and balances the sugar.
White onions
Add savory depth and body as they cook down into the sauce.
Ground cloves
Add warm, aromatic spice that stands out in the sauce.
Black pepper
Adds gentle heat and sharpness to the spice blend.

The step that matters

Add the cloves late. Ground cloves are very potent and can turn bitter and harsh with prolonged heat, so adding them near the end keeps their aroma clean. The method lists them both in the pot and after cooking, so follow the late addition.

Swap the onion
