What each ingredient does

Butter
Provides the rich fat and flavour that forms the body of the sauce.
Lemon juice
Adds acidity that brightens the rich butter and balances its fattiness.

The step that matters

Decanting the melted butter. Melted butter separates into clear butterfat, milky water and milk solids. Pouring off only the clear fat leaves the solids and water behind, so the sauce stays smooth and clear rather than cloudy.
