Why it works: Cucumber and walnut match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 380 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Cucumber Pickles
Ingredients
Directions
Pour a hot brine made of 1 cup of coarse sea salt and 1 gallon of water over the cucumbers for three mornings in a row.
On the fourth morning, pour hot vinegar mixed with dissolved alum into the cucumbers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Firm cucumbers
- Provide the main body and crisp texture that the pickling process works on.
- Coarse sea salt
- Draws water out of the cucumbers and firms them in the hot brine.
- Vinegar
- Adds sourness and acidity that preserves the cucumbers and gives the pickle its tang.
- Alum
- Helps the cucumber tissue stay firm and crisp after the hot vinegar is added.
The step that matters
Dissolving the alum in the hot vinegar. Alum must be fully dissolved before it goes over the cucumbers, or undissolved lumps can cause uneven firming. The hot vinegar helps it dissolve and spread evenly through the jar.
Swap the walnut

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