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

What each ingredient does

Ripe tomatoes
Provide the main body and flavour of the pickle.
Cider vinegar
Acidity that preserves the tomatoes and gives the pickle its sharp taste.
Egg white
Spread on the paper to form a airtight seal over the jar.

The step that matters

Pour the boiling vinegar over the tomatoes. The vinegar must be at a full boil so its acidity and heat reach the tomatoes and help preserve them. Vinegar that is too cool may leave the tomatoes unsafe to store.

Swap the tomato

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

  1. Mustardfits better
  2. Cucumberfits better
  3. Capsicumfits better
  4. Tomatothe original

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