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 dish, providing the savory base for the dressing.
Sweet oil
Adds fat and richness, carrying the flavour of the other seasonings.
Vinegar
Adds acidity that brightens the dressing and balances the richness of the oil.
Mustard
Adds sharp flavour and helps emulsify the oil and vinegar into the dressing.
Hard-boiled egg yolk
Adds richness and body to the dressing, helping it thicken.

The step that matters

Mix the dressing into an emulsion. Oil and vinegar separate unless mustard helps bind them. Mixing them well before filling the shells keeps the dressing smooth and evenly seasoned instead of greasy and separated.

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.
