What each ingredient does
- Milk
- Forms the liquid base that the peptonizing agent acts on to produce the finished drink.
- Pancreas extract or peptonizing agent
- Enzymes that partly break down milk proteins, giving the milk a predigested, lighter character.
The step that matters
Heat gradually until it boils, stirring constantly. Heating gradually and stirring keeps the milk from scorching on the pan bottom and from forming a skin or curdling unevenly. Constant stirring spreads heat evenly, so the mixture boils uniformly without burnt flavour.
