Why it works: Mustard and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,356 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Crab Salad
Ingredients
Directions
Prepare
Drain canned crabs or boil fresh crabs and pick the meat into pieces.
Beat the butter until creamy, then add the egg yolks, mustard, Cayenne pepper, and salt.
Make the dressing

Set aside to cool.
Serve
Line a salad bowl with crisp lettuce, add the crab meat, and pour the dressing over just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify with the butter and thicken the dressing as it cooks.
- Butter
- Adds richness and body to the dressing.
- Vinegar
- Adds acidity that balances the rich dressing and helps it thicken when boiled.
- Crab meat
- Provides the main protein and sweet, delicate flavor of the salad.
- Dry mustard
- Adds sharp flavor and helps stabilize the emulsified dressing.
The step that matters
Boil the dressing until thickened. Egg yolks thicken and set when heated, but overheating or curdling can make the dressing grainy. Cook gently, stirring, until it coats a spoon, then cool before serving.
