What each ingredient does

Batter
Starch thickens the hot liquid into a smooth, cohesive sauce.
Butter
Fat adds richness and a rounded, smooth mouthfeel to the sauce.
Parsley
Adds fresh, green aroma and flavour to the finished sauce.

The step that matters

Thicken with batter. Starch needs heat to swell and thicken. Adding batter to boiling liquid can clump if not evenly dispersed, and the gentle simmer afterward lets the starch fully hydrate for a smooth texture.
