Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Sauce for Salmon and Other Fish
Ingredients
Directions
Make the base
Heat the milk in a saucepan until it boils.
Mix the cornstarch with a little cold water to form a slurry, then add it to the boiling milk.
Stir in the butter and the liquor from the salmon.
Finish the sauce
Remove from heat and add the beaten egg, stirring well.
Season with mace and cayenne pepper to taste.
Cover and let it stand in hot water for 3 minutes.
Finally, stir in the lemon juice and serve immediately over the salmon.

Mace and pepper barely smell alike, yet cooks put them together in 12,257 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that the thickened sauce is built on.
- Cornstarch
- Thickens the milk into a smooth, pourable sauce as it heats.
- Butter
- Adds fat for richness and a smooth, silky mouthfeel.
- Raw egg
- Sets gently with the warm sauce, adding body and richness.
- Lemon juice
- Adds acidity that brightens the rich, creamy sauce.
The step that matters
Adding the beaten egg off the heat. Egg proteins set at about 70°C and can scramble if added to a boiling sauce. Removing the pan from the heat first and stirring well lets the egg thicken the sauce smoothly.
Swap the mace
How well each one fits the dish's main ingredients (milk, butter, egg, lemon, pepper):
- Parsleyfits better
- Nutmegfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against milk, butter, egg, lemon, pepper. Candidates are from the same food group and used in at least 100 recipes.
