Why it works: Mustard and vinegar are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

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):
- Capsicumfits about as well
- Mustardthe original
- Asparagusfits less well
- Spinachfits less well
