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

How well each one fits the dish's main ingredients (cucumber, pepper, mustard, olive, cider, vinegar, sugar):

  1. Lettucefits better
  2. Capsicumfits better
  3. Horseradishfits better
  4. Onionthe original

Fit is the average pairing score against cucumber, pepper, mustard, olive, cider, vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
