No. 189 How to Make Gruel With Pearl Barley
Put four ounces of pearl barley in a saucepan with two quarts of cold water and a small stick of cinnamon, and set the whole to boil very gently by the side of the fire (partly covered with the lid) for two hours; then add the sugar and the wine, boil all together a few minutes longer, and then strain the gruel through a colander into a jug, to be kept in a cool place until required for use; when it can be warmed up in small quantities.
As this kind of gruel is a powerful cordial, it is to be borne in mind that it should never be administered unless ordered by a medical man.
