Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Crab flesh
- Forms the main body of the salad and supplies its savoury, sweet flavour.
- Oil
- Adds moisture and richness, and carries the flavour of the other seasonings.
- Vinegar
- Adds acidity that brightens the rich crab and balances the oil.
- Hard boiled egg yolks
- Bind with the oil and vinegar to form a creamy, smooth dressing that coats the crab.
- Cayenne pepper
- Adds gentle heat and aroma that sharpens the flavour of the crab.
The step that matters
Mixing the crab with oil, vinegar and egg yolks. The yolks help the oil and vinegar blend into a smooth, creamy dressing rather than separating. Mixing gently keeps the crab flesh in flakes so the salad stays light and textured.
