What each ingredient does
- Liver of fish
- Forms the main body of the sauce, giving it its rich flavor and smooth texture.
- Melted butter
- Adds fat and richness, helping the sauce feel smooth and silky on the palate.
The step that matters
Boil the pounded liver with melted butter and salt. Once the liver is pounded smooth, boiling it with butter needs attention so the sauce stays smooth and does not separate or scorch. Keep the heat controlled and stir so the fat stays emulsified with the liver.
