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 ↓
Crisp Cucumber Pickles
Ingredients
Directions
Make the brine
Combine cider vinegar, salt, sugar, ground mustard, alum, diced horseradish, and spices in a large bowl.
Pickle

Ensure the cucumbers are fully submerged in the vinegar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cider vinegar
- Provides the acidity that preserves the cucumbers and gives the pickles their sharp flavor.
- Salt
- Draws moisture out of the cucumbers and seasons the brine, helping them stay firm.
- Sugar
- Balances the sharpness of the vinegar with a touch of sweetness.
- Ground mustard
- Adds pungent, sharp flavor to the brine.
- Alum
- Helps keep the cucumbers firm and crisp during pickling.
- Horseradish
- Adds a pungent, sharp heat that flavors the brine.
The step that matters
Keep the cucumbers fully submerged. Any cucumber left above the vinegar brine is exposed to air, where spoilage microbes and mold can grow. Full submersion keeps the vegetables covered by the acidic liquid, which slows spoilage and keeps the pickles uniformly preserved.
