Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Form the bulk of the pickle and supply its body once cooked until tender.
- Onions
- Add savory flavour and aroma that deepens during cooking.
- Vinegar
- Provides acidity that preserves the pickle and sharpens its flavour.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
The step that matters
Squeeze the salted mixture dry. Salt draws water out of the vegetables overnight. Squeezing off that liquid before adding vinegar keeps the pickle from becoming watery and lets it absorb the vinegar and sugar properly.
Swap the onion
How well each one fits the dish's main ingredients (tomato, pepper, mustard, celery, vinegar, sugar):
- Capsicumfits better
- Lettucefits better
- Horseradishfits better
- Onionthe original
Fit is the average pairing score against tomato, pepper, mustard, celery, vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
