    Shared aroma: isobutyraldehyde (malty, green).

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.

What each ingredient does

Milk
Adds moisture and richness, diluting the gruel while providing fat and milk sugars.
Liquor pancreaticus
Enzyme preparation that breaks down starches and proteins, partly pre-digesting the mixture.
Bicarbonate of soda
Raises the alkalinity of the mixture, helping the pancreatic enzymes work.

The step that matters

Keep the mixture warm after adding the liquor pancreaticus. The enzymes act most effectively at body-like warmth. Keeping the mixture warm in a covered jug lets digestion proceed, while the cover limits heat loss and skin formation on the surface.
