Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 27,047 recipes mention both. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Hollandaise Sauce
Ingredients
Directions
Prepare the sauce
In a small bowl, cream the butter with a wooden spoon.
Add the egg yolks one at a time, beating well after each addition.
Stir in the lemon juice, salt, and cayenne pepper.
About five minutes before serving, add the boiling water.
Cook and thicken
Place the bowl in a saucepan of boiling water and stir rapidly until it thickens like boiled custard.

Egg and lemon share little aroma chemistry, yet 44,316 recipes mention both: they likely 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
- Butter
- Provides fat that makes the sauce rich and smooth when emulsified.
- Egg yolks
- Emulsify with the butter and thicken the sauce as they cook gently.
- Lemon juice
- Adds acidity that balances the richness of the butter and yolks.
The step that matters
Thickening over boiling water. Egg yolks set at around 65 to 70 degrees Celsius, so the sauce must be stirred rapidly over heat that is hot but not too hot. If it overheats, the yolks scramble and the sauce curdles.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
