Ingredients
Directions
Prepare the pulp
Select perfect fruit and cook it in porcelain, never metal.
Strain the fruit to obtain the pulp.
Cook and season
Add 1 pound of sugar, mace, cinnamon, cloves, and peppercorns to the pulp.
Boil the mixture down to one third of its volume, then skim off the spices.
Add sugar and boil until thick.
Finish and bottle
Adjust consistency with hot vinegar and bottle for use.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fruit pulp
- Provides the main body, flavour and colour of the ketchup as it cooks down.
- Sugar
- Adds sweetness and, as it boils down, helps thicken the ketchup and preserve it.
- Hot vinegar
- Adds acidity that brightens the flavour and helps preserve the finished ketchup.
- Cinnamon
- Adds warm aroma to the spiced flavour of the ketchup.
- Cloves
- Adds pungent aroma to the spiced flavour of the ketchup.
The step that matters
Boiling the mixture down. Reducing the pulp to one third of its volume concentrates sugar and fruit solids, which thickens the ketchup and helps it keep. Stopping too early leaves it thin and prone to spoiling, while overcooking can scorch the sugars.
Swap the mace
How well each one fits the dish's main ingredients (peach, sugar, cinnamon, clove, vinegar):
- Allspicefits better
- Nutmegfits better
- Cardamomfits better
- Macethe original
Fit is the average pairing score against peach, sugar, cinnamon, clove, vinegar. Candidates are from the same food group and used in at least 100 recipes.
