Why it works: Horseradish and mustard 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 ↓
New York Cucumber Pickles
Ingredients
Directions
Make the brine
Make a brine by mixing 1 pint of coarse sea salt with 1 gallon of water.
Pour the boiling brine over small cucumbers and let them stand for 24 hours.
Pack the jars
Rinse and drain the cucumbers, then pack them into glass jars.
In each jar, add a small piece of horseradish, a small white onion, and 1 teaspoon each of black mustard seed, white mustard seed, celery seed, and juniper berries.
Fill the jars with boiling vinegar and seal quickly.
For each gallon of vinegar, add ½ pound of sugar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Small cucumbers
- Form the pickle itself, becoming crisp and tangy as they cure in brine and vinegar.
- Coarse sea salt
- Draws water out of the cucumbers and seasons them during the brine stage.
- Boiling vinegar
- Provides the acidity that preserves the cucumbers and gives the pickle its sharp flavour.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
The step that matters
Pour the boiling brine over the cucumbers and let them stand 24 hours. The salt must dissolve fully in the water so the brine is evenly strong. Uneven or weak brine lets the cucumbers soften or spoil instead of firming and curing.
