Why it works: Lettuce and mustard 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 ↓
Salmon Mayonnaise
Ingredients
Directions
Make the sauce
Make the sauce first. Pound the yolks of the hard-boiled eggs until smooth, then add the raw yolks and mix well.
Gradually add the salad oil while stirring continuously.
Add the salt, mustard, sugar, and then the cream, mixing well.
Finally, add the vinegar drop by drop, continuing to stir until fully combined.
Prepare the salad
Wash and dry the lettuce, then flake the salmon, removing bones and skin.
Tear the lettuce into small pieces if the leaves are large.
Assemble and serve
Layer the lettuce and salmon in a round dish, pouring some sauce between each layer.
Garnish with slices of cucumber.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raw egg yolks
- Emulsify the oil and cream into a thick, smooth sauce.
- Hard-boiled egg yolks
- Add body and richness to the sauce, helping it stay smooth.
- Salad oil
- Provides fat that forms the body of the mayonnaise when added slowly.
- Cream
- Adds moisture and softness, giving the sauce a milder, looser texture.
- Tarragon vinegar
- Adds acidity that brightens the sauce and balances the richness of the oil.
- Cold salmon
- Provides the main protein, flaked into the layers of the dish.
The step that matters
Adding the oil gradually. Oil must be added slowly while stirring so it disperses into tiny droplets held by the egg yolk emulsifiers. Adding it too fast can cause the sauce to split and separate.
