Why it works: Mustard and horseradish match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,832 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Small Cucumber Pickles
Ingredients
Directions
Prepare the cucumbers
Wash and wipe the cucumbers carefully. Place them in jars.
In a porcelain-lined kettle, bring enough water to a boil to cover the cucumbers. Stir in enough salt to create a brine that will float an egg.
Pour the boiling brine over the cucumbers and let them stand for 24 hours.
Make the pickling liquid
Remove the cucumbers, wipe each one carefully without bruising, and place them in clean jars.
In a porcelain kettle, add enough vinegar to cover the cucumbers, along with the sliced onion, cloves, mustard seed, and mace. Bring this mixture to a boil and pour it over the pickles.
Add the chopped horseradish and let the mixture cool.
Rest and store
The pickles will be ready to use in two weeks and will keep all winter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the crisp body that the brine and vinegar transform into pickles.
- Coarse sea salt
- Draws water out of the cucumbers and seasons them through the brine.
- Vinegar
- Adds acidity that preserves the pickles and gives them their sharp flavor.
- Mustard seed
- Contributes pungent, aromatic flavor to the pickling liquid.
- Horseradish
- Adds sharp, pungent heat that deepens as the pickles rest.
The step that matters
Pouring the boiling brine over the cucumbers. The brine must be made with enough salt to float an egg, so it is strong enough to draw water from the cucumbers and keep them firm. Weak brine can leave pickles soft.
Swap the mace
How well each one fits the dish's main ingredients (cucumber, egg, vinegar, onion, clove, mustard, horseradish):
- Capersfits better
- Tarragonfits better
- Dillfits better
- Macethe original
Fit is the average pairing score against cucumber, egg, vinegar, onion, clove, mustard, horseradish. Candidates are from the same food group and used in at least 100 recipes.
