Why it works: Vinegar and mustard 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 ↓
Lobster Salad
Ingredients
Directions
Prepare the lobster
Boil the lobster until cooked, then cool and remove the shell.
Cut the lobster meat into cakes and chill on ice for 1 hour.
Make the mayonnaise
For the mayonnaise, stir the cold egg yolk in a bowl.
Slowly add olive oil drop by drop, then by half teaspoonfuls until thickened.
Add vinegar or lemon juice, salt, pepper, and cayenne to the mayonnaise.
Keep the mayonnaise on ice until ready to serve.
Serve
Pour the mayonnaise over the chilled lobster and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Emulsifies the olive oil into the mayonnaise, giving it a thick, stable texture.
- Olive oil
- Forms the fat phase of the mayonnaise, giving it richness and body.
- Lobster
- Provides the main protein and sweet flavour of the salad.
- Vinegar or lemon juice
- Adds acidity that brightens the mayonnaise and balances the richness of the oil.
The step that matters
Adding the olive oil to the egg yolk. Oil must be added very slowly at first, because the yolk can only emulsify small droplets at a time. Adding oil too fast breaks the emulsion, leaving a runny, separated sauce instead of a thick mayonnaise.
Swap the mustard
The recipe marks mustard as optional. How well each one fits the dish's main ingredients (lobster, egg, olive, vinegar, pepper):
- Capsicumfits better
- Mustardthe original
- Cucumberfits about as well
- Spinachfits less well
Fit is the average pairing score against lobster, egg, olive, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
