Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Make up the bulk of the pickle and supply the main body of the texture.
- Onions
- Add savory bulk and sweetness that softens during long cooking.
- Coarse sea salt
- Draws water out of the tomatoes and onions, firming them before pickling.
- Vinegar
- Provides the acidity that preserves and sharpens the pickle.
- Mustard
- Adds pungency and a sharp, tangy flavor to the pickle.
The step that matters
Boiling the pickle. Boiling for 10 to 15 minutes lets the vinegar and spices penetrate the vegetables and mellow the sharpness. Too short a boil leaves the pickle harsh and underflavored.
Swap the tomato
How well each one fits the dish's main ingredients (onion, pepper, clove, mustard, allspice, vinegar, sugar):
- Horseradishfits better
- Shallotfits better
- Capsicumfits better
- Tomatothe original
Fit is the average pairing score against onion, pepper, clove, mustard, allspice, vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
