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 provides its flavour.
Mixed mustard
Adds sharp, pungent flavour that balances the richness of the crab.
Vinegar
Adds acidity that brightens the flavour of the crab meat.
Salad oil
Adds fat that coats the crab meat and gives it a smoother mouthfeel.

The step that matters

Mix the crab meat thoroughly with the dressing. Even coating ensures every bite is seasoned and moist. Uneven mixing leaves bland pockets and dry patches, since the oil and vinegar must be spread through the delicate meat rather than just laid on top.

Swap the mustard

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

  1. Capsicumfits better
  2. Mustardthe original
  3. Okrafits less well
  4. Horseradishfits less well

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