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

What each ingredient does

Picked crab meat
Provides the main savoury protein and bulk of the salad.
Egg yolks
Emulsify with the butter and thicken the dressing as they gently cook, giving it a custard-like body.
Butter
Adds richness and a smooth, creamy mouthfeel to the dressing.
Mustard powder
Adds sharp, pungent flavour and helps stabilise the emulsion.
Vinegar
Adds acidity that brightens the rich butter and yolk dressing.

The step that matters

Heating the dressing over low heat. Egg yolks thicken at a gentle temperature, but too much heat scrambles them and the dressing curdles. Constant stirring spreads the heat evenly and keeps the custard smooth.

Swap the lettuce
