Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Make up most of the relish and provide its main texture and body.
- White onions
- Add savoury depth and a sharp aroma that mellows during boiling.
- Granulated sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Vinegar
- Supplies acidity for a sharp tang and helps preserve the relish.
- Turmeric
- Gives the relish its yellow colour and a mild, earthy flavour.
The step that matters
Boiling for 20 minutes. Boiling all ingredients together for the full time cooks the vegetables until tender while the vinegar and sugar thicken and blend the flavours. Boiling too long can turn the cucumbers soft and mushy, while too short a boil leaves the onions raw-tasting and the mixture less stable for storage.
Swap the onion
How well each one fits the dish's main ingredients (cucumber, sugar, celery, pepper, mustard, vinegar, turmeric):
