Ingredients
Directions
Salt and scald
Combine chopped tomatoes, peppers, cabbage, cucumbers, onions, and celery in a bowl.
Mix in coarse sea salt and let stand for 12 hours.
Drain the mixture thoroughly and scald it in 2 quarts of vinegar.
Pack and cover
Drain again and pack the mixture into jars.
Once cold, pour over the remaining 2 quarts of vinegar mixed with horseradish, mace, cinnamon, allspice, mustard, cayenne, celery seed, and mustard seed.
Cover with a plate to keep the mixture submerged in vinegar, then cover the top with a thick cloth.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Makes up the bulk of the pickle; its firm flesh holds its shape in the vinegar.
- Cabbage
- Adds bulk and crunch that softens only partly after scalding.
- Coarse sea salt
- Draws water out of the vegetables, leaving them firmer and less watery.
- Vinegar
- Its acidity preserves the mixture and gives the pickle its sharp flavour.
- Horseradish
- Adds sharp, pungent heat to the pickle.
- Onions
- Add sweetness and a sharp bite to the mixture.
The step that matters
Keep the vegetables submerged in vinegar. Pieces left above the liquid are exposed to air, which encourages spoilage and mould. The plate holds everything under the vinegar, and the cloth covers the top of the jar to protect it while it keeps.
