Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Salmon and Mayonnaise Sauce
Ingredients
Directions
Cook the salmon

Finish and serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Firm, flaky protein that sets and becomes opaque as it cooks.
- Egg yolks
- Act as the emulsifier that holds the oil and vinegar together as a thick sauce.
- Salad oil
- Supplies the fat that gives the mayonnaise its rich, creamy body.
- Vinegar
- Adds acidity that sharpens the flavor and helps stabilize the emulsion.
- Made mustard
- Adds sharpness and helps the yolks and oil bind into a stable emulsion.
The step that matters
Add the oil slowly to the yolks. Oil must be added drop by drop at first so the yolk lecithin can surround the droplets and form a stable emulsion. Adding it too fast can cause the sauce to split and stay runny.
Swap the mustard
How well each one fits the dish's main ingredients (salmon, egg, vinegar, butter, pepper, parsley):
