Why it works: Mustard and celery are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 4,169 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Cucumber Pickles
Ingredients
Directions
Brine and scald
Soak the cucumbers in salt water for 3 days, covered.
Boil a little alum in the vinegar and pour it over the cucumbers while hot; repeat 3 or 4 times.
Bottle
When ready to bottle, add the ground mustard and the chow-chow (discarding its vinegar).
Mix in enough cold vinegar to cover the pickles well.
Seal in glass jars.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- The main vegetable, which softens and absorbs the brine and vinegar as it pickles.
- Vinegar
- Provides the acidity that sharpens flavor and keeps the pickles preserved.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- White mustard seed
- Adds a mild, sharp mustard flavor to the brine.
- Black mustard seed
- Adds a stronger, more pungent mustard flavor.
- Celery seed
- Adds a savory, aromatic celery note.
The step that matters
Pouring the hot alum vinegar over the cucumbers. Alum helps firm the cucumber tissue so the pickles stay crisp rather than going soft. Repeating the hot pour lets the alum and heat penetrate the cucumbers, so each repetition matters for texture.
Swap the onion
How well each one fits the dish's main ingredients (cucumber, mustard, celery, pepper, sugar, vinegar):
- Horseradishfits better
- Lettucefits better
- Radishfits better
- Onionthe original
Fit is the average pairing score against cucumber, mustard, celery, pepper, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
