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

What each ingredient does

Pickles
Form the main body of the jar and supply the crisp, sour base flavor.
Powdered alum
Helps the pickle slices stay firm and crisp during soaking.
Sharp vinegar
Provides acidity that preserves the pickles and gives them their tang.
Olive oil
Adds fat and a smooth mouthfeel to the packed jars.

The step that matters

Add powdered alum. Alum is a firming agent that hardens pectin in the pickle tissue, so it helps slices stay crisp. Measure it carefully, since too much can leave a harsh or bitter taste.

Swap the onion

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

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

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