Better Recipe for Tomato Catsup
Ingredients
Directions
Prepare the tomatoes
Gather the tomatoes when quite ripe.
Cut them in thin slices.
Put a thick layer of tomatoes and a layer of salt alternately in a stone jar until full.
Make the ketchup
Boil it gently for half an hour.
Rub it through a hair sieve.
To every gallon add four roots of horseradish scraped, a small onion stuck full of cloves, quarter ounce of mace, quarter ounce cloves, quarter ounce nutmeg, one ounce allspice, two pods red pepper, or one ounce black pepper.
Boil all together.
When done add at the rate of half a pint of vinegar to every gallon of catsup, and one pint of wine to every three quarts.
Bottle and seal
Bottle it as soon as sufficiently cool.
Cork it immediately, keeping it tight.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes (in the method)
- Provide the main body, pulp and flavour of the ketchup.
- Vinegar
- Adds acidity that gives the ketchup its tang and helps preserve it.
- Wine
- Adds acidity and depth of flavour to the finished ketchup.
- Horseradish
- Adds a sharp, pungent bite to the sauce.
- Allspice
- Adds warm, aromatic spice flavour.
- Black pepper
- Adds sharp heat and aroma to the seasoning.
The step that matters
Boil it gently for half an hour. Gentle simmering softens the tomatoes so they can be pushed through a sieve smoothly. Boiling too hard can scorch the pulp and dull its fresh flavour.
Swap the mace
How well each one fits the dish's main ingredients (clove, nutmeg, allspice, pepper, wine, vinegar, horseradish):
- Cinnamonfits better
- Thymefits better
- Tarragonfits better
