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

What each ingredient does

Crabs
Provide the main meat, which is cooked by steaming and then picked out for the salad.
Melted butter
Adds richness and fat to the dressing, carrying flavour across the crab meat.
Vinegar
Adds acidity that brightens the dressing and helps keep the crabs from scorching during steaming.
Mustard
Adds sharp, pungent flavour that balances the richness of the butter.

The step that matters

Add enough vinegar before steaming. The record says vinegar is poured in to prevent burning. Without enough liquid in the pot, the crabs and the bottom of the kettle can scorch before they finish cooking.

Swap the mustard

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

  1. Capsicumfits about as well
  2. Mustardthe original
  3. Onionfits less well
  4. Horseradishfits less well

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