Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cucumbers
Provide the crisp, crunchy body of the pickles.
Coarse sea salt
Draws water out of the vegetables, firming them and reducing moisture before pickling.
White onions
Add sharpness and aroma that flavour the pickled mixture.
Olive oil
Coats the vegetables and carries the flavour of the spices through the pickles.
Vinegar
Acidifies the mixture, preserving the vegetables and giving them their tang.
Sugar
Balances the acidity with sweetness and helps firm the pickles.

The step that matters

Drying after the overnight salting. Salt draws water out of the cucumbers and onions. Rinsing and draining thoroughly removes the excess salt and liquid, so the pickles stay crisp and are not overly salty in the jar.

Swap the onion
