Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the main bulk and crisp texture of the sauce.
- White onions
- Add savory sharpness and aroma that balance the vinegar.
- Coarse sea salt
- Draws water out of the cucumbers and onions, firming them during draining.
- Cider vinegar
- Supplies acidity that preserves the sauce and gives it its tang.
- Black pepper
- Adds pungent heat and aroma to the sauce.
The step that matters
Draining the cucumbers and onions with salt. Salt draws water out of the vegetables through osmosis. If they are not drained long enough, the sauce stays watery and dilutes its flavor and tang.
Swap the onion
How well each one fits the dish's main ingredients (cucumber, cider, vinegar, pepper, mustard, clove):
- Horseradishfits better
- Lettucefits better
- Radishfits better
- Onionthe original
Fit is the average pairing score against cucumber, cider, vinegar, pepper, mustard, clove. Candidates are from the same food group and used in at least 100 recipes.
