No. 188 How to Prepare Arrow-root
Mix a piled-up dessert-spoonful of arrow-root with half a gill of cold water, and pour this into a small saucepan containing nearly half a pint of boiling water, four lumps of sugar, and a glass of wine; stir the arrow-root while it is boiling on the fire for a few minutes, and then give it to the patient.
Observe that it is essential to perfection in the preparation of arrow-root, and, indeed, of all farinaceous kinds of food, that the whole of the ingredients used in the preparation should be boiled together.
