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 ↓
Auburn Cucumber Pickles
Ingredients
Directions
Prepare the cucumbers
Rinse cucumbers carefully to avoid bruising the skins.
Pack cucumbers in a jar, layering with salt.
Cover with boiling water and let stand for 24 hours.
Drain and dry cucumbers with a soft towel.
Make the brine and pack
In a preserving kettle, combine vinegar, sugar, chopped peppers, alum, and mustard seed.
Bring the mixture to a boil and pour over the cucumbers.
Store pickles in glass jars or a stone jar, placing a horseradish or grape leaf on top to prevent mold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the crisp, bulky body of the pickle that the brine permeates.
- Coarse sea salt
- Draws water out of the cucumbers, firming them and helping preserve texture.
- Cider vinegar
- Supplies the acidity that preserves the pickles and gives them their sharp flavour.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Alum
- Helps cucumbers stay firm during pickling.
- White mustard seed
- Adds a pungent, aromatic flavour to the brine.
The step that matters
Rinse cucumbers carefully. Bruised skins let the brine and spoilage microbes penetrate unevenly, leading to soft spots and faster spoilage in the finished pickles.
