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

What each ingredient does

Small cucumbers
Form the main body of the pickle mix, becoming crisp-tender in the brine.
Vinegar
Provides the acidity that preserves and sharpens the pickles.
Brown sugar
Balances the sharp vinegar with sweetness and a deeper flavor.
Flour
Thickens the hot vinegar mixture into a smooth, coating sauce.
Ground mustard
Adds sharp, pungent flavor and color to the sauce.

The step that matters

Stir the flour and mustard into the hot vinegar slowly. Pouring the hot liquid slowly while stirring keeps the flour from clumping. Lumps won't dissolve evenly, so the sauce may come out grainy instead of smooth.

Swap the onion

How well each one fits the dish's main ingredients (cucumber, cauliflower, tomato, pepper, vinegar, sugar, flour):

  1. Capsicumfits better
  2. Broccolifits better
  3. Mustardfits better
  4. Onionthe original

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