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

What each ingredient does

Cucumbers
Provide the bulk and fresh, crisp texture; draining their water keeps the chutney from becoming runny.
Onions
Add sharp, pungent flavour that mellows and balances the cucumber.
Vinegar
Adds acidity that sharpens the flavour and helps preserve the chutney.
Horseradish
Contributes a sharp, pungent heat that gives the chutney its bite.

The step that matters

Strain the cucumbers well. Cucumbers hold a lot of water. If it is not drained off, the chutney will be watery and dilute its flavour. Straining before combining keeps the texture thick and the seasoning concentrated.

Swap the onion

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