Why it works: Cider and vinegar are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,431 recipes. Both carry 4-ethyl-2-methoxyphenol, which smells smoky, clove. The science ↓
Sliced Cucumber Pickle
Ingredients
Directions
Prepare
Peel the green rind off the cucumbers and slice them thick.
In a large bowl, layer the cucumber slices and small onion pieces, sprinkling a little salt between each layer.
Let the mixture stand for six hours to drain.
Pack and seal
After draining, pack the cucumbers and onions into jars, adding cayenne pepper between each layer.
Cover the contents with strong cider vinegar.
Top each jar with 2 tablespoons of good sweet oil and seal tightly.
Finish
After two weeks, pour off the vinegar and replace it with fresh vinegar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the crisp, bulky vegetable body that the salt and vinegar soften and flavour.
- Small onions
- Add pungent aroma and flavour that mellows during the long steeping in vinegar.
- Coarse sea salt
- Draws water out of the cucumbers and onions during draining, firming the texture.
- Strong cider vinegar
- Acidifies and preserves the vegetables, giving the pickles their sharp tang.
The step that matters
Draining with salt. Salting and standing for six hours draws out excess water. If the vegetables are not drained well, the extra moisture dilutes the vinegar and the pickles can turn soft and spoil sooner.
Swap the onion
How well each one fits the dish's main ingredients (cucumber, pepper, cider, vinegar):

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