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 ↓

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.
- Corn starch
- Thickens the hot milk into a glossy, pourable sauce as it gelatinizes.
- Butter
- Adds fat for a rich mouthfeel and smooth texture.
- Raw egg
- Adds body and richness to the sauce when it is gently stirred in.
- Lemon juice
- Adds acidity that brightens the rich sauce.
The step that matters
Add the beaten egg off the heat. Egg proteins set at high heat and can curdle or scramble in the sauce. Adding the beaten egg off the heat lets it thicken the sauce gently and keep it smooth.
Swap the mace
How well each one fits the dish's main ingredients (milk, corn, butter, egg, lemon, pepper, salmon):
- Parsleyfits better
- Dillfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against milk, corn, butter, egg, lemon, pepper, salmon. Candidates are from the same food group and used in at least 100 recipes.
