Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ham
- Adds savory flavour and fat to the warm dressing.
- Vinegar
- Provides the sharp acidity that defines the dressing.
- Sugar
- Balances the acidity of the vinegar with sweetness.
- Onion
- Adds aromatic sharpness that mellows as it cooks in the pan.
The step that matters
Pour the hot dressing over the lettuce and serve immediately. The dressing must be hot when poured so the lettuce softens slightly and absorbs flavour. Lettuce left sitting in the dressing loses its crispness and becomes limp, so serving right away keeps the contrast between warm dressing and crisp leaves.
Swap the onion
How well each one fits the dish's main ingredients (ham, vinegar, sugar, pepper, lettuce):
