What each ingredient does

Patent barley flour
Thickens the liquid as its starch swells with heat, giving the gruel its body.

The step that matters

Simmer while stirring continuously. Barley starch can settle and scorch on the base of the pan, and constant stirring keeps it dispersed and smooth while it thickens as it simmers.
