What each ingredient does

Butter
Adds richness and a smooth, silky body to the sauce.
Lemon
Supplies sharp acidity and fragrant oil from the peel, cutting the richness.
Liver
Forms the main body of the sauce and gives it its savory flavor.
Parsley leaves
Adds a fresh, green herbal aroma that balances the rich liver and butter.

The step that matters

Warm together without boiling. Boiling can overheat the butter, causing it to separate, and can toughen the liver's proteins, leaving the sauce grainy instead of smooth. Gentle heat keeps the emulsion stable and the texture tender.
