Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yellow cucumbers
- Provide the main body of the pickle, and salting and draining firm them up for a crisp bite.
- Vinegar
- Adds sharp acidity that gives the pickle its tang and helps preserve it.
- Sugar
- Sweetens the brine and balances the sharpness of the vinegar.
- Red peppers
- Add mild sweetness, color, and a little fresh flavor to the jars.
- Mustard seed
- Adds a sharp, warm aroma and a pungent flavor to the pickle.
The step that matters
Drain the cucumbers after salting and standing. Salt draws water out of the cucumbers by osmosis. If they are not drained well, excess liquid dilutes the vinegar brine and the pickles can turn soft and watery.
Swap the cucumber
How well each one fits the dish's main ingredients (vinegar, sugar, pepper, mustard):
- Horseradishfits better
- Capsicumfits better
- Radishfits about as well
- Cucumberthe original
Fit is the average pairing score against vinegar, sugar, pepper, mustard. Candidates are from the same food group and used in at least 100 recipes.
