Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuces
- Forms the bulk of the salad and provides its crisp, fresh leaf texture.
- Hard-boiled egg yolks
- Pressed through a sieve, they make the dressing smooth and rich, adding body and fat.
- Cold white sauce
- Binds the sieved yolks into a creamy dressing that coats the leaves.
- Vinegar
- Adds acidity that brightens the rich dressing and balances its fat.
- Capers
- Add a sharp, briny flavour that cuts through the richness of the dressing.
The step that matters
Rubbing the yolks through a fine sieve. Yolks pressed through a fine sieve break into very small particles that blend smoothly into the white sauce. Unsieved or coarse yolks leave lumps and a grainy texture in the dressing.
