Make the dressing

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold dressed fish
- Forms the main body of the salad, providing its protein and flavour.
- Hard boiled egg yolks
- Mashed with mustard and cream, they form a smooth, rich emulsified dressing.
- Cream
- Adds richness and a smooth, silky texture to the dressing.
- Vinegar
- Adds acidity that sharpens the dressing and balances the richness of the yolks and cream.
- Mustard
- Adds sharpness and helps bind the dressing as an emulsifier.
- Onions
- Boiled until tender, they add mild sweetness and soft texture to the salad.
The step that matters
Blend in the cream and vinegar until smooth. Adding cream and vinegar gradually to the mashed yolks and mustard helps form a stable, smooth emulsion. Adding them all at once can cause the dressing to split or turn grainy.
Swap the onion
