Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beets
- Form the bulk of the pickles and provide their color and earthy flavor.
- Vinegar
- Provides the acidity that preserves the beets and gives the pickles their tang.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Horseradish
- Adds sharp, pungent heat that stands up to the sweetness and acidity.
The step that matters
Seal the jar tightly. An airtight seal keeps air and contaminants out, which helps the pickles keep their flavor and resist spoilage while the vinegar and sugar work on the beets.
Swap the horseradish
How well each one fits the dish's main ingredients (pepper, sugar, vinegar):
- Capsicumfits better
- Mustardfits better
- Cabbagefits better
- Horseradishthe original
Fit is the average pairing score against pepper, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
