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
