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 ↓
Green Cucumber Pickles
Ingredients
Directions
Brine
Dissolve the salt in enough hot water to cover the cucumbers and pour over them while boiling hot.
Let stand for twenty-four hours.
Reheat the brine for three successive mornings.
Scald and spice
On the fourth morning, drain the brine and pour boiling water over the cucumbers to cover; let stand for another twenty-four hours.
If the cucumbers are plump, place them in a jar and add the spices in bags.
Heat vinegar enough to cover the cucumbers with a piece of alum and pour it over hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the pickle itself; their firm flesh softens slowly as the brine works through them.
- Coarse salt
- Draws water out of the cucumbers and preserves them in the brine.
- Vinegar
- Adds acidity that sharpens the flavor and helps preserve the pickles.
- Cinnamon
- Contributes warm, sweet aroma to the spiced liquid.
- Cloves
- Adds warm, pungent aroma to the spiced liquid.
The step that matters
Reheating the brine each morning. Brining relies on salt slowly drawing water out and firming the cucumbers. Repeated heating keeps the brine hot and active while the cucumbers gradually take up flavor, so letting it cool or skipping mornings weakens the process.
