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

What each ingredient does

Crab meat
Forms the main body of the salad and gives it its substance and flavor.
Sweet oil
Supplies the fat that makes the dressing rich and gives it a smooth mouthfeel.
Vinegar
Adds acidity that sharpens the flavor and balances the richness of the oil.
Hard-boiled egg yolk
Helps bind the oil and vinegar into a thick, creamy dressing.
Mustard
Contains compounds that help hold the oil and vinegar together as an emulsion.

The step that matters

Combine the dressing well. Oil and vinegar naturally separate. Thorough mixing with the egg yolk and mustard breaks the oil into tiny droplets that stay suspended, giving a smooth, cohesive dressing instead of a greasy layer on top of the crab.

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.
