Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Roe
- Forms the main body of the sauce and gives it its distinctive flavour.
- Egg yolk
- Emulsifies with the butter to give the sauce a smooth, rich body.
- Butter
- Adds fat for richness and a silky texture once melted into the sauce.
The step that matters
Stir in the egg yolk and melted butter. Adding the fat gradually while stirring helps the yolk emulsify, so the sauce stays smooth instead of splitting into greasy separated layers.
