Why it works: Lettuce and mustard match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 1,356 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Oyster Salad
Ingredients
Directions
Prepare the oysters and lettuce
Parboil the oysters in their own liquor, then drain and cut them into bits.
Mix the oysters with the torn lettuce.
Boil 3 eggs for 20 minutes, then plunge them into cold water.
Separate the whites from the yolks; chop the whites and add to the oysters and lettuce.
Make the dressing
Mash the yolks (both cooked and raw) together in a bowl.
Slowly pour in the olive oil while stirring vigorously until the mixture resembles mayonnaise.
Add mustard, salt, lemon juice, and pepper to taste.
Fold in the stiffly beaten egg whites just before serving.
Serve
Pour the dressing over the oysters and lettuce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main seafood flavour and tender texture once parboiled and cut into bits.
- Eggs
- Yolks bind with oil into an emulsified dressing; whites add lightness and body.
- Olive oil
- Supplies fat and richness, emulsifying with the yolks to form the creamy dressing.
- Lettuce
- Forms the crisp, leafy base that gives the salad its fresh bulk.
- Mustard
- Helps stabilise the emulsion and adds a sharp, savoury tang.
- Lemon juice
- Adds acidity that brightens the dressing and balances the richness of the oil.
The step that matters
Slowly pour in the olive oil while stirring vigorously. Oil must be added gradually so droplets disperse and are held by the egg yolk's lecithin; adding it too fast breaks the emulsion, leaving a greasy, separated dressing instead of a creamy mayonnaise-like sauce.

Fit is the average pairing score against oyster, lettuce, egg, olive, mustard, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
