Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the crisp, bulky body of the pickles.
- Cider vinegar
- Provides the acidity that preserves and sharpens the pickles.
- Sugar
- Balances the sharp vinegar with sweetness.
- Olive oil
- Adds fat and a richer mouthfeel to the pickled vegetables.
- Mustard seed
- Contributes a sharp, aromatic pungency to the brine.
- Onions
- Add savory flavor and a little bite to the mix.
The step that matters
Drain well after the salt brine. Excess brine left on the cucumbers and onions dilutes the vinegar mixture and can make the pickles soggy and overly salty. Thorough draining keeps the texture crisp and the flavor balanced.
Swap the onion
