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 ↓
Pickled Cucumbers
Ingredients
Directions
Prepare
Wash and drain the cucumbers.
If not pickling all cucumbers at once, soak them in cold water for 24 hours before pickling.
Pack and cover
In a jar, layer cucumbers, allspice, cloves, horseradish, and mustard seed.
Continue layering until the jar is full.
Pour in enough vinegar to cover the cucumbers.
Add 2 teaspoons of pulverized alum to the jar.
Check
Check the jars in a day or two and add more vinegar if needed.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- The main vegetable that becomes crisp-tender as it pickles in the vinegar.
- Good vinegar
- Provides the acidity that preserves the cucumbers and gives the pickles their sharp flavor.
- Pulverized alum
- Helps the cucumbers stay firm and crisp during pickling.
- Allspice
- Adds warm, aromatic spice flavor to the pickling liquid.
- Cloves
- Add warm, aromatic spice flavor to the pickles.
The step that matters
Keep the cucumbers fully covered with vinegar. Cucumbers that poke above the liquid can spoil and soften, because exposed surfaces are not protected by the acid. Checking after a day or two and topping up the vinegar keeps every piece submerged as the level drops.
Swap the clove
How well each one fits the dish's main ingredients (cucumber, allspice, horseradish, mustard, vinegar):
- Capersfits better
- Tarragonfits better
- Dillfits better
- Clovethe original
Fit is the average pairing score against cucumber, allspice, horseradish, mustard, vinegar. Candidates are from the same food group and used in at least 100 recipes.
