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

What each ingredient does

Crab meat
Provides the main body and sweet, delicate flavor of the salad.
Sweet oil
Carries the flavors and adds richness and moisture to the salad.
Hard-boiled egg yolk
Mashed into the oil to emulsify and thicken the dressing, giving it a creamy body.
Mustard
Adds sharp flavor and helps stabilize the emulsion of oil and vinegar.
Vinegar
Adds acidity that brightens the flavor and balances the richness of the oil.

The step that matters

Mash the egg yolk into the oil mixture and combine well. Egg yolk and mustard help oil and vinegar form a stable emulsion. If the yolk is not thoroughly blended, the dressing can separate and look greasy rather than creamy and cohesive.

Swap the mustard

How well each one fits the dish's main ingredients (crab, meat, pepper, vinegar, egg):

  1. Capsicumfits about as well
  2. Mustardthe original
  3. Asparagusfits less well
  4. Spinachfits less well

Fit is the average pairing score against crab, meat, pepper, vinegar, egg. Candidates are from the same food group and used in at least 100 recipes.
