What each ingredient does

Farinaceous material (oatmeal or quaker oats)
Provides the starch that thickens the boiled gruel into a body.
Cold milk
Adds moisture and richness, and cools the boiling gruel before the enzymes are added.
Liquor pancreaticus
Pancreatic enzymes that partly break down proteins and starches, softening the gruel.
Sodium bicarbonate
Raises the mixture's alkalinity, which helps the enzymes work as a peptonizing agent.

The step that matters

Adding the enzymes to a cooled gruel. Pancreatic enzymes are damaged by strong heat, so the gruel must be cooled by the milk before the liquor pancreaticus is stirred in. Adding it while the mixture is still boiling can weaken its action and leave the gruel less broken down.
