Directions
Prepare the tomatoes
Cut the tomatoes in half and place them in a dish.
Sprinkle a little salt over the tomatoes and let them stand for 3-4 hours.

Strain the mixture through a colander and return it to the kettle.
Season and bottle

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Form the bulk of the ketchup and provide its body, acidity and flavour once stewed.
- White wine
- Adds acidity and a sharp tang that balances the sweetness of the tomatoes.
- Cloves
- Contribute warm, aromatic spice notes to the ketchup.
- Nutmeg
- Adds warm, aromatic spice notes to the ketchup.
- Mace
- Adds a delicate, warm aroma to the ketchup.
The step that matters
Boil the mixture for 1 hour. Long boiling concentrates the tomato liquid and drives off water, thickening the sauce and mellowing the spices. Too little boiling leaves the ketchup thin and harsh-tasting, and it may not keep well once bottled.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, clove, nutmeg, mace, white wine):
- Carrotfits better
- Capsicumfits better

Fit is the average pairing score against pepper, clove, nutmeg, mace, white wine. Candidates are from the same food group and used in at least 100 recipes.
