Why it works: Lemon and nutmeg match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 11,318 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Sauce Hollandaise
Ingredients
Directions
Prepare
Boil the vinegar with the peppercorns until reduced by half.
Strain and set aside to cool.
Make the sauce
In a saucepan, mix half of the butter cut into small pieces, the egg yolks, salt, nutmeg, and the cooled vinegar.
Set the saucepan over boiling water and stir continuously with a wooden spoon until smooth.
Strain the mixture into another saucepan and return it to the boiling water, beating steadily.
Gradually add the remaining butter in small pieces and the Velouté.
When the sauce is light and frothy, remove from heat, squeeze in a little lemon juice, and serve immediately with fish.

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 the sauce as they cook gently over heat.
- Butter
- Adds richness and fat that gives the sauce its smooth, silky body.
- Vinegar
- Adds acidity that sharpens the flavour and helps stabilise the emulsion.
- Velouté
- Adds body and stability to the sauce, helping it hold together.
The step that matters
Keeping the heat gentle while whisking the yolks. Egg yolks thicken at moderate temperatures but scramble if overheated. Stirring over boiling water and beating steadily keeps the sauce smooth, while butter added slowly lets the emulsion form without curdling.
Swap the lemon
