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 the cucumbers
Make a brine that will float an egg and heat it until boiling.
Pour the hot brine over the cucumbers and let them stand for 24 hours, or make a cold brine and let it stand for 48 hours.
Wipe the black specks from each cucumber.
Make the pickling syrup
Add enough vinegar to cover the cucumbers and a small lump of alum.
Place the cucumbers in a brass kettle with the cold vinegar and heat slowly, turning them from the bottom several times.
Let them stand for 24 hours.
If needed, add more vinegar to cover the cucumbers.
In a muslin bag, tie together 3 pints of brown sugar, 3 cups of mustard seed, a handful of celery seed, ginger root, and a piece of alum.
Scald the bag with vinegar and pour it over the cucumbers hot.
Finish
Add green peas and horseradish cold, if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the main body of the pickle, which firms and absorbs the brine and spice flavour.
- Brown sugar
- Adds sweetness that balances the sharp acidity of the vinegar.
- Vinegar
- Provides the acidity that preserves the cucumbers and gives the pickle its sharp tang.
- Mustard seed
- Contributes a sharp, pungent flavour to the pickling liquid.
- Alum
- Helps the cucumbers stay firm and crisp during long soaking and heating.
The step that matters
Heating the cucumbers slowly in the vinegar. Heating too fast or too long can soften the cucumbers and make them mushy. Slow heat and turning them help them warm evenly and keep their firm texture while they absorb the vinegar.
Swap the ginger
How well each one fits the dish's main ingredients (cucumber, egg, vinegar, sugar, mustard, celery, walnut):
