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

What each ingredient does

Cucumbers
Provide the main crisp vegetable body of the relish.
Cider vinegar
Supplies acidity that preserves the relish and gives it its tang.
Sugar
Balances the sharp acidity with sweetness.
Flour
Thickens the paste so it coats the vegetables.
Mustard
Adds sharp flavor and pungency to the paste.
Turmeric
Gives the relish its yellow color and earthy flavor.

The step that matters

Cook the paste until thick. Flour thickens only as it heats and needs to cook long enough to lose its raw taste and set. Undercooked flour leaves the paste thin and floury, so it fails to coat the vegetables.

Swap the onion

How well each one fits the dish's main ingredients (cucumber, celery, beans, cauliflower, pepper, mustard, turmeric):

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

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