Orange Jelly
425. Squeeze the juice from the oranges, and to every pint of the juice add a pound of sugar and a quarter of an ounce of dissolved isinglass. The Russian isinglass is the kind to use for this purpose. Boil and skim it till a jelly is formed, which you may tell by letting a drop fall in a glass of cold water, and if it falls to the bottom in a mass the jelly is done. Or, take a little out in a spoon and expose it to the cool air for a few minutes.
