Why it works: Cucumber and onion match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 6,050 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Cucumbers, to Pickle
Ingredients
Directions
Salt the vegetables
Slice large cucumbers and place them in a pewter dish.
Slice 2 large onions thinly and layer them with the cucumbers, adding a handful of coarse sea salt between each layer.
Cover with another pewter dish and let stand for 24 hours.
Drain the cucumbers in a colander and place them in a jar.
Pickle and seal
Cover with white wine vinegar and let stand for 4 hours.
Boil the vinegar with salt, then add mace, whole pepper, and sliced ginger.
Pour the boiling vinegar over the cucumbers, cover tightly, and let cool.
Once cool, seal the jar and they can be used in a few days.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Large cucumbers
- Provide the main crisp vegetable body that becomes tender-crisp and pickled.
- Coarse sea salt
- Draws water out of the cucumbers and onions, firming texture and concentrating flavor.
- White wine vinegar
- Acidity that preserves the vegetables and gives the pickle its sharp, tangy flavor.
- 2 large onions
- Add sharp aromatic flavor that mellows during the salting and pickling.
The step that matters
Drain the cucumbers well after salting. Salt draws out a lot of liquid from the cucumbers and onions. If they are not drained thoroughly, the extra water dilutes the vinegar and can leave the pickle soggy and weakly flavored.
Swap the mace
How well each one fits the dish's main ingredients (cucumber, onion, white wine, vinegar, pepper, ginger):
- Garlicfits better
- Turmericfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against cucumber, onion, white wine, vinegar, pepper, ginger. Candidates are from the same food group and used in at least 100 recipes.
