Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green sweet peppers
- Give the pickle its main bulk and fresh, mildly sweet vegetable flavor.
- White onions
- Add savory depth and aroma that mellows during the boil.
- Green tomatoes
- Contribute tartness and body to the chopped vegetable mixture.
- Vinegar
- Provides the acidity that preserves the pickle and sharpens its flavor.
- Sugar
- Balances the vinegar's sharpness with sweetness.
The step that matters
Wring out the excess moisture. Vegetables hold a lot of water; if it is not removed, it dilutes the vinegar brew and leaves the pickle watery and less firm.
Swap the onion
How well each one fits the dish's main ingredients (pepper, tomato, vinegar, sugar):
- Capsicumfits better
- Cucumberfits better
- Mustardfits better
- Onionthe original
Fit is the average pairing score against pepper, tomato, vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
