Why it works: Butter and egg are a kitchen classic. They rank in the top 17% of all ingredient pairs, and 118,967 recipes mention both. Both carry decanal, which smells soap, orange peel. The science ↓
Hollandaise Sauce
Ingredients
Directions
Prepare the butter
Wash the butter in cold water using a spoon.
Divide the butter into three pieces.
Make the sauce
In a saucepan, combine one piece of butter, egg yolks, and vinegar.
Place the saucepan in a larger pot of boiling water and stir constantly with a whisk until the butter melts.
Add the second piece of butter and stir until thickened, then add the third piece.
Finally, stir in the boiling water.

Egg and vinegar share little aroma chemistry, yet 12,922 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 fat, giving the sauce its smooth, creamy body.
- Egg yolks
- Emulsify the butter and thicken the sauce as they gently cook.
- Vinegar
- Adds acidity that brightens the flavour and balances the rich butter.
The step that matters
Keep the heat gentle while whisking in the butter. Egg yolks scramble if they get too hot, which curdles the sauce. Gentle heat from the water bath lets the yolks thicken slowly while the butter emulsifies into them smoothly.
