What each ingredient does
- Milk
- Forms the liquid base and supplies the proteins and sugars the mixture works on.
- Well-boiled gruel
- Adds starch and body, giving the mixture a thicker, more substantial texture.
- Carbonate of soda
- Raises the alkalinity of the mixture, which changes how the milk proteins behave.
- Liquid pancreaticus
- Contains enzymes that partly break down proteins and starches, altering flavor and texture.
The step that matters
Maintain the mixture at the same temperature for 3 hours. Enzyme activity depends on steady warmth. Too cold slows the breakdown, and too hot can destroy the enzymes before they have worked on the mixture.
