Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the main crisp, bulky body of the relish.
- Silver onions
- Add savory bulk and a mild sharp flavor to the relish.
- Vinegar
- Acidifies the vegetables, creating the pickled tang and helping preserve them.
- Turmeric
- Gives the relish its yellow color and a mild earthy aroma.
- Red peppers
- Add color, mild sweetness and a little heat to the relish.
The step that matters
Salting and draining the vegetables. Salt draws water out of the cucumbers and onions through osmosis. Draining well removes that liquid, so the relish stays crisp and the vinegar is not diluted.
Swap the onion
How well each one fits the dish's main ingredients (cucumber, vinegar, turmeric, pepper, sugar):
- Mustardfits better
- Capsicumfits better
- Cauliflowerfits better
- Onionthe original
Fit is the average pairing score against cucumber, vinegar, turmeric, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
