Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Small cucumbers
- Form the main body of the pickles, staying firm and crisp after brining.
- White vinegar
- Provides the acidity that preserves the pickles and gives them their sharp flavor.
- White mustard seed
- Adds pungent, earthy heat that flavors the hot vinegar mixture.
- Black mustard seed
- Adds sharper, more pungent heat to the vinegar mixture.
- Turmeric
- Gives the pickles their yellow color and a mild earthy aroma.
- White onions
- Add sweetness and texture to the mixed pickles.
The step that matters
Let the vinegar mixture cool before adding the mustard. Prepared mustard is added when the brine is cold, because heat can dull its sharp flavor and change its texture. Adding it to hot vinegar risks a weaker, muddier result.
Swap the onion
