Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cucumbers
Form the bulk of the relish and provide its crisp, fresh texture.
Coarse sea salt
Draws moisture out of the cucumbers and onions so the relish stays crisp.
Vinegar
Provides acidity that preserves the relish and gives it its sharp tang.
Sugar
Balances the sharpness of the vinegar with sweetness.
Onions
Add pungent flavor and bulk to the relish.
Ground horseradish
Contributes a sharp, pungent heat to the relish.

The step that matters

Drain the mixture after standing. Salting and standing pulls a lot of water out of the cucumbers and onions. Draining removes that liquid so the hot brine does not dilute, and the relish stays crisp rather than soggy.

Swap the onion

How well each one fits the dish's main ingredients (cucumber, horseradish, pepper, vinegar, sugar, turmeric):
