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 ↓
Sour Cucumber Pickles
Ingredients
Directions
Salt the cucumbers
Wash the cucumbers and layer them in a large jar with coarse sea salt, repeating layers until all cucumbers are used.
Cover the jar with a lid; no water is needed, and more cucumbers can be added later.
Desalt and drain
When ready to prepare, take the cucumbers and place them in a large pan.
Cover the cucumbers with cold water and heat on the stove to draw out the salt.
Once hot, pour off the water and replace it with fresh water, repeating this process 3-4 times.
Let the cucumbers sit until cool enough to handle, about 1-2 days, then drain on a cloth.
Pack and pickle
Pack the cucumbers into 2-quart jars with red peppers and horseradish.
In a kettle, heat enough cider vinegar to cover the cucumbers and add 1 cup of brown sugar for every 2 quarts of vinegar.
Once boiling, pour the vinegar mixture over the pickles and seal while 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; salting and rinsing firm and season them.
- Coarse sea salt
- Draws water out of the cucumbers, firming their texture and preserving them.
- Cider vinegar
- Provides the acidity that makes the pickles sour and helps preserve them.
- Brown sugar
- Balances the sourness of the vinegar with sweetness and depth.
The step that matters
Desalting the cucumbers. Cucumbers salted for days hold a lot of salt; repeated changes of cold water, heated to draw salt out, keep the final pickles from being harsh and overly salty. Skipping rinses leaves them too salty.
Swap the horseradish
How well each one fits the dish's main ingredients (cucumber, cider, vinegar, sugar, pepper):

Fit is the average pairing score against cucumber, cider, vinegar, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
