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 ↓
Salmon Mayonnaise
Ingredients
Directions
Prepare the fish
Turn out the tin of salmon.
Arrange the fish on a plate, removing all skin and bones.
Make the mayonnaise
In a small bowl, combine the egg yolk and mustard, stirring with a wooden spoon.
Slowly add the salad oil while stirring vigorously until the mayonnaise thickens.
Once thickened, add the tarragon vinegar and lemon juice, thinning with cold stock if necessary.
Assemble and serve
Prepare some lettuce and lay it on a dish.
Arrange the salmon on top.
Pour the mayonnaise sauce over the salmon and garnish with cucumber slices and capers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Emulsifies the oil and vinegar into a thick, stable mayonnaise.
- Salad oil
- Provides fat that, emulsified with the yolk, gives the sauce its body and richness.
- Salmon
- Supplies the main protein and flavour of the dish.
- Tarragon vinegar
- Adds acidity that brightens the sauce and balances the richness of the oil.
- Lemon juice
- Adds acidity and fresh aroma that lift the flavour of the sauce.
The step that matters
Adding the oil slowly while stirring. Oil must be added gradually so droplets are dispersed and held by the egg yolk's lecithin. Adding it too fast can break the emulsion, leaving a thin, oily sauce that will not thicken.
Swap the lemon
How well each one fits the dish's main ingredients (salmon, egg, mustard, tarragon, vinegar, lettuce, cucumber):
- Avocadofits better
- Limefits about as well
- Lemonthe original
- Cherryfits about as well
Fit is the average pairing score against salmon, egg, mustard, tarragon, vinegar, lettuce, cucumber. Candidates are from the same food group and used in at least 100 recipes.
