Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Provide the crisp, watery base that the dressing coats.
- Coarse sea salt
- Draws water out of the cucumbers, softening them and concentrating their flavor.
- Vinegar
- Adds acidity that brightens the dressing and balances the sugar.
- Sugar
- Adds sweetness that offsets the vinegar's sharpness.
- Sweet oil or ham gravy
- Adds fat and richness that carries the flavor of the dressing.
The step that matters
Drain the cucumbers slightly after salting. Salting pulls out a lot of liquid. Draining only slightly keeps some moisture so the dressing stays loose, but too much water left in would thin it and dilute the vinegar and sugar.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (cucumber, ham, vinegar, sugar, pepper):
- Mustardfits better
- Capsicumfits better
- Lettucefits better
- Onionthe original
Fit is the average pairing score against cucumber, ham, vinegar, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
