Why it works: Cucumber and horseradish match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 640 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Cucumber Pickles
Ingredients
Directions
Brine
Choose cucumbers and place them in brine that will float an egg.
Boil the brine for 3 mornings, pouring it over the pickles hot each time.
On the third morning, drain the brine from the pickles.
Vinegar and alum
Mix half water and half good vinegar, boil for 3 mornings, pouring it over the pickles hot.
Add a big piece of alum and cover with grape leaves in the jars.
Pack and store
On the seventh morning, drain the pickles and place them in a stone jar.
Pour boiling hot cider vinegar over the pickles, then add a piece of horseradish and alum.
Spice to your liking, cover with grape leaves, and seal the jar.
Let the pickles stand for 3 to 6 weeks before using.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Firm base that stays crisp through repeated hot brine and vinegar pourings.
- Alum
- Helps the pickles stay firm and crisp during the long hot soaking.
- Cider vinegar
- Provides the acidity that preserves the pickles and gives them their sharp flavor.
- Horseradish
- Adds a sharp, pungent aroma and flavor to the finished pickles.
The step that matters
Pouring boiling hot brine or vinegar each morning. The pickles must be kept hot through repeated pourings so they gradually absorb salt and acid and firm up. If the liquid cools or the pouring is skipped, the cucumbers may soften or spoil.
Swap the grape
How well each one fits the dish's main ingredients (cucumber, egg, cider, vinegar, horseradish):

- Grapethe original
Fit is the average pairing score against cucumber, egg, cider, vinegar, horseradish. Candidates are from the same food group and used in at least 100 recipes.
