Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the butter and thicken the sauce as they set gently with heat.
- Butter
- Adds fat that makes the sauce rich and smooth once emulsified.
- French vinegar
- Provides acidity that balances the richness of the butter and yolks.
The step that matters
Keep the heat gentle while adding the butter. Egg yolks scramble if they get too hot, and the sauce can split. Gentle, constant stirring lets the butter emulsify into the yolks and keeps the sauce smooth.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
