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 ↓
Gherkins, or Young Cucumbers
Ingredients
Directions
Brine the cucumbers
Select young cucumbers the size of a finger and place them in unglazed stone jars.
Dissolve ¼ pound of coarse sea salt in 1 quart of boiling water and let it cool.
Cover the cucumbers with the brine and set the jars on the hearth for 2-3 days until they turn yellow.
Pour off the brine.
Drain the cucumbers.
Green and spice
Scald and dry the jar.
Return the cucumbers to the jar and cover them with vinegar.
Set the jar again before the fire for 8-10 days until the cucumbers turn green.
Pour off the vinegar.
Prepare a new pickle with fresh vinegar and the spices.
Add 2 ounces of black pepper, 1 ounce of ginger, 1 ounce of salt, ½ teaspoon of cayenne, and 1 ounce of mustard seeds to the vinegar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Young cucumbers are the base that softens and takes on the pickle flavour and colour.
- Coarse sea salt
- Draws water out of the cucumbers and seasons them in the brine.
- Vinegar
- Acidity preserves the cucumbers and gives the pickle its sharp flavour.
- Black pepper
- Adds sharp, warm pungency to the pickling liquid.
- Mustard seeds
- Add a sharp, pungent flavour to the vinegar.
The step that matters
Pouring off the brine before the vinegar stage. Cucumbers must be fully drained and the jar scalded and dried before vinegar is added. Leftover brine dilutes the vinegar and can spoil the pickle, so the jar and cucumbers need to be as dry as possible.
Swap the ginger
How well each one fits the dish's main ingredients (vinegar, cucumber, pepper, mustard):
- Tarragonfits better
- Dillfits better
- Capersfits better
- Gingerthe original
Fit is the average pairing score against vinegar, cucumber, pepper, mustard. Candidates are from the same food group and used in at least 100 recipes.
