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 on the palate.
- Egg yolks
- Their proteins set gently with heat, thickening the sauce and giving it body.
- Lemon juice
- Adds acidity that brightens the sauce and balances the richness of the butter.
The step that matters
Cook in a double boiler until creamy. Egg yolks thicken at gentle heat but can scramble if overheated. Cooking over simmering water, not direct heat, keeps the sauce smooth and creamy.

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).
