Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Salmon
Provides the main protein and flaky body of the salad.
Mealy potatoes
Their starch breaks down when mashed, giving the dressing a smooth, thick body.
Egg yolks
Their fat and emulsifying lecithin help bind the butter and mustard into a smooth dressing.
Butter
Adds richness and fat that softens the dressing's texture and flavour.
Mustard
Adds sharp flavour and helps stabilise the emulsified dressing.
Vinegar
Adds acidity that brightens the dressing and thins it to a cream-like consistency.

The step that matters

Adding the vinegar gradually. Vinegar must be added slowly so the emulsion of yolk, butter and mustard can absorb it. Adding it all at once can thin the dressing too much or cause it to split, so the cream consistency is lost.

Swap the mustard

How well each one fits the dish's main ingredients (salmon, egg, potato, butter, vinegar, cream):
