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 ↓
Cucumber Pickles
Ingredients
Directions
Prepare the cucumbers
Wash and dry the cucumbers.
Place them in a jar with salt and alum, then cover with boiling water.
Seal the jar and let it stand for 24 hours.
Remove the cucumbers from the jar. Wipe them dry.

Fill the jar with strong boiling vinegar until it is two-thirds full of cucumbers. Cover the jar closely.
Let it cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Small cucumbers
- Are the main vegetable; their firm flesh holds crispness through brining and pickling.
- Coarse sea salt
- Draws water out of the cucumbers and seasons them, firming the texture for pickling.
- Strong boiling vinegar
- Provides the acidity that preserves the cucumbers and gives the pickle its sharp flavour.
- Alum
- Helps the cucumbers stay firm and crisp during the long brining step.
The step that matters
Let the cucumbers stand in the salt and alum brine for 24 hours. Salt draws water out of the cucumbers and alum helps keep the flesh firm; if the brine is too weak or the time is cut short, the pickles can soften and spoil. Keeping the jar sealed while it stands holds the brine around the cucumbers.
