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 sauce
Heat the milk in a saucepan until it boils.
Mix the cornstarch with cold water, then add it to the boiling milk to thicken.
Stir in the salmon liquor and butter until combined.
Remove from heat and add the beaten egg, stirring well.
Season with mace and cayenne pepper, then cover and let stand in hot water for 3 minutes.
Finish and serve
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 starch thickens into a smooth sauce.
- Cornstarch
- Swells in hot liquid to thicken the sauce into a glossy, pourable body.
- Raw egg
- Sets gently when heated, adding body and richness to the sauce.
- Butter
- Adds fat for a smoother, richer mouthfeel.
- Lemon juice
- Adds acidity that brightens the flavour of the sauce.
The step that matters
Add the egg off the heat. Raw egg proteins set when heated, so removing the pan from the heat first and stirring well helps the egg blend smoothly instead of scrambling.
Swap the mace
How well each one fits the dish's main ingredients (milk, salmon, butter, egg, lemon, pepper):
- Parsleyfits better
- Dillfits better
- Nutmegfits better
- Macethe original
Fit is the average pairing score against milk, salmon, butter, egg, lemon, pepper. Candidates are from the same food group and used in at least 100 recipes.
