Peptonized Milk Gruel

Ingredients

Directions

Make the gruel

  1. Boil the farinaceous material in water to make a thick gruel.

  2. Add an equal quantity of cold milk to the boiling gruel.

Peptonize and finish

  1. Stir in 3 teaspoons of liquor pancreaticus and 20 grams of sodium bicarbonate.

  2. Cover and let it stand in a warm place for 2 hours.

  3. Boil for 5 minutes and then strain before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Farinaceous material
Forms the thick gruel body that the enzymes act on.
Cold milk
Supplies the protein and fat that the enzymes break down, giving the gruel its base.
Liquor pancreaticus
Pancreatic enzymes that break down milk proteins and starches into softer, more digestible forms.
Sodium bicarbonate
Raises the alkalinity so the enzymes can work effectively during standing.

The step that matters

Standing in a warm place with the enzymes. Enzyme activity depends on temperature and alkalinity. The mixture must stand warm for the full two hours so the enzymes can break down proteins and starches; too cool or too short a rest leaves the gruel only partly peptonized.
