Why it works: Butter and nutmeg are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 24,377 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Sauce Hollandaise
Ingredients
Directions
Make the base
Pour the vinegar into a small saucepan and add the peppercorns and salt.
Boil the liquid until it reduces to half, then let it cool.
Make the sauce
Add the well-beaten egg yolks, 4 ounces of butter, more salt if necessary, and nutmeg.
Set the saucepan over very low heat and stir until thickened like cream, then remove from heat.
Place the saucepan in another pan with warm water beside the fire.
Whisk the sauce briskly, adding small pieces of the remaining butter until the sauce is light and smooth.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify with the butter and thicken gently into a rich, smooth sauce.
- Butter
- Adds richness and fat that, emulsified with the yolks, gives the sauce its smooth body.
- Vinegar
- Provides acidity that balances the richness of the butter and yolks.
The step that matters
Stirring over very low heat. Egg yolks thicken at gentle heat but scramble if they get too hot. Keeping the heat very low and stirring constantly lets the yolks thicken into a smooth emulsion instead of curdling.
Swap the nutmeg
How well each one fits the dish's main ingredients (vinegar, egg, butter):
- Tarragonfits better
- Parsleyfits better
- Capersfits about as well
- Nutmegthe original
Fit is the average pairing score against vinegar, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
