Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vinegar
- Provides the sharp acidity that preserves the cucumbers and gives the pickles their tang.
- Sugar
- Balances the sourness of the vinegar and rounds out the brine's flavour.
- Grated horseradish
- Adds a pungent, sharp heat that flavours the brine and the cucumbers.
- Ground mustard
- Contributes a sharp, pungent flavour that deepens the brine.
- Small dill cucumbers
- The main vegetable, which absorbs the brine's acidity and flavour as it sits.
The step that matters
Let the pickles sit for 3 to 4 days, stirring occasionally. The cucumbers must stay fully submerged and in contact with the brine so acidity and salt reach every piece. Occasional stirring evens out the brine and helps prevent uneven or spoiled spots.
Swap the dill
How well each one fits the dish's main ingredients (cucumber, vinegar, sugar, horseradish, mustard):
- Capersfits better
- Tarragonfits about as well
- Dillthe original
- Allspicefits less well
Fit is the average pairing score against cucumber, vinegar, sugar, horseradish, mustard. Candidates are from the same food group and used in at least 100 recipes.
