Why it works: Cucumber and mustard match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 2,281 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Pickled Cucumbers
Ingredients
Directions
Brine and yellow
Make a brine with enough coarse sea salt in water to float an egg.
Pour the brine over the cucumbers.
Cover with cabbage leaves.
Let sit for a week until yellow.
Drain the water.
Green the cucumbers
Place cucumbers in a porcelain kettle with fresh leaves and a piece of alum.
Cover with vine leaves and a dish or cloth to trap steam.
Fill the kettle with clear water.
Heat gently over moderate heat for several hours.
If cucumbers are not a pretty green, repeat the heating process.
Once green, remove cucumbers.
Drain on a sieve.
Pickle and spice
Transfer to a clean stone jar.
Spice vinegar with cloves, mace, mustard seed, and sugar.
Boil for 6 to 8 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- The main vegetable that is pickled and turned green during the heating process.
- Coarse sea salt
- Draws water out of the cucumbers and seasons them during the brining stage.
- Alum
- Helps the cucumbers firm up and keep their green colour during heating.
- Sugar
- Adds sweetness to the spiced vinegar, balancing its sharpness.
The step that matters
Heating the cucumbers gently. Heating over moderate heat for several hours keeps the cucumbers from turning soft or dull. Boiling hard can break down their texture, so the cook must watch the colour and repeat gently if needed.
Swap the mace
How well each one fits the dish's main ingredients (cucumber, cabbage, clove, mustard, sugar):
- Cinnamonfits better
- Allspicefits better
- Capersfits better
- Macethe original
Fit is the average pairing score against cucumber, cabbage, clove, mustard, sugar. Candidates are from the same food group and used in at least 100 recipes.
