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

What each ingredient does

Cucumbers
Form the bulk of the salad and release moisture during draining.
Onions
Add sharp flavour and aroma that mellows during pickling.
Salt
Draws water out of the cucumbers and onions during draining, firming the texture.
Mustard seed
Contributes pungent, slightly bitter flavour and crunch.
Vinegar
Acidifies the mixture, preserving it and giving the salad its tang.

The step that matters

Let the mixture drain for 8 hours. Salt draws water out of the cucumbers and onions. If they drain too briefly, the salad stays watery and the pickle dilutes once vinegar is added, weakening texture and flavour.

Swap the onion

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

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

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