Why it works: Butter and lemon are a kitchen classic. They rank in the top 16% of all ingredient pairs, and 41,227 recipes mention both. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Hollandaise Sauce
Ingredients
Directions
Make the sauce
Cream the butter in a bowl.
Add the egg yolks and beat well together.
Slowly add the lemon juice, salt, paprika, and hot water while continuing to cream the mixture.
Cook in a double boiler, stirring constantly until the sauce thickens to a creamy consistency.
Remove from heat and beat with a whisk for about five minutes.
Serve
Serve hot with fish or cold meats.

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
- Adds richness and a smooth, velvety mouthfeel to the emulsion.
- Egg yolks
- Emulsify with the butter and set into a thick, creamy structure when gently heated.
- Lemon juice
- Adds acidity that balances the richness and brightens the flavor.
The step that matters
Cook in a double boiler, stirring constantly. Egg yolks thicken with gentle heat but scramble if they get too hot. Constant stirring over indirect heat keeps the temperature low and even so the sauce thickens smoothly instead of curdling.
Flavor stand-ins for the lemon
How well each one fits the dish's main ingredients (butter, egg):

Fit is the average pairing score against butter, egg. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
