Why it works: Mustard and horseradish match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,832 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Red Cabbage Pickle
Ingredients
Directions
Prepare the cabbage
Sprinkle salt over the sliced cabbage and let it sit in the sun or a warm place for 3 days.
Boil together ½ pint of vinegar and ½ gallon of water.
Pour the boiling mixture over the cabbage and let it soak for 1 day.
Make the pickle and jar
Once the cabbage feels crisp and the salt is out, mix mustard seed, celery seed, horseradish, brown sugar, pepper, salt, 1 quart of vinegar, tamarack, and chopped onions in a pot.
Pour the boiling vinegar mixture over the cabbage.
Seal tightly in jars and let it sit for a few weeks before using.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red cabbage
- Forms the crisp, crunchy body of the pickle once salted and soaked.
- Vinegar
- Provides the acidity that preserves the cabbage and gives the pickle its sharp flavour.
- Coarse sea salt
- Draws water out of the cabbage, softening it and helping it take up the brine.
- Mustard seed
- Adds pungent, sharp flavour that mellows during the weeks of sitting.
- Horseradish
- Contributes a sharp, pungent heat that deepens as the pickle matures.
The step that matters
Pouring the boiling vinegar mixture over the cabbage. The cabbage must be well drained of its salty liquid and the brine kept hot so it penetrates the cabbage evenly. Pouring too little heat or skipping the salt-drawing stage leaves the pickle soft and unevenly flavoured.
