What each ingredient does

Fresh butter
Adds richness and a smooth, velvety body as it melts into the liquid.
Sweet milk
Provides creaminess and body, forming the base of the sauce.
Parsley
Supplies the main herbal flavour and aroma of the sauce.

The step that matters

Gradually add the butter.. Adding butter in small amounts to hot liquid lets it melt and emulsify evenly, giving a smooth sauce. Adding it all at once can cause it to separate and look greasy.
