What each ingredient does

Milk
Provides the liquid base and the proteins that the peptonizing agent breaks down.
Peptonizing agent
Enzymes that partly break down milk proteins, making the milk easier to digest.

The step that matters

Heat gradually until boiling, stirring constantly. Heating slowly and stirring keeps the milk from scorching or forming a skin on the bottom of the pan, and the enzymes need to work evenly through the liquid.
