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 ↓
Sliced Cucumber Pickle
Ingredients
Directions
Brine
Place cucumbers in a jar or pail and cover with boiling water and salt.
Cover tightly and repeat this process for three mornings.
Make the pickling vinegar
On the fourth morning, scald enough cider vinegar to cover cucumbers.
Add the piece of alum and the horseradish root to the vinegar.
Tie mustard, cloves, and cinnamon in a small muslin bag and add to the vinegar.
Pack and seal
Slice cucumbers into ½ inch thick pieces and place them in glass jars.
Pour the scalding vinegar mixture over the cucumbers and seal tightly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- The main vegetable; repeated salting and brining firm and season the flesh.
- Cider vinegar
- Provides the acidity that preserves the cucumbers and gives the pickle its sharp flavor.
- Coarse sea salt
- Draws water out of the cucumbers and seasons them during the brining stage.
- Alum
- Helps the cucumbers stay firm and crisp during pickling.
- Horseradish root
- Adds pungent, sharp aroma and heat to the vinegar.
The step that matters
Pouring scalding vinegar over the cucumbers and sealing. The vinegar must be hot and the jars sealed tightly so the acid penetrates the cucumbers and keeps the pickles from spoiling. Cool or loosely sealed jars leave the pickles vulnerable to spoilage.
