Fletcher’s Digestive Biscuits
Ingredients
Directions
The book says “a cool oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Mix 128 grains of pepsine with 16 ounces of biscuit dough or paste.
Form the mixture into biscuits, each weighing one-eighth of an ounce.
Bake the biscuits in a moderate oven at 350°F (175°C) without exceeding the temperature that would impair the digestive ferments.
Alternatively, take already baked biscuits and add pepsine mixed with sugar, gum, or egg white, then dry if necessary.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
