No. 195 How to Prepare Isinglass Jelly
Put one ounce and a-half of isinglass, with two ounces of lump sugar and half a pint of water, into a small stewpan, and stir the whole on the fire while it boils gently for ten minutes; then remove the jelly from the fire, add the juice of three oranges, and the thin pared rind of one orange; stir well together for five minutes, strain through a muslin into a basin, and set the jelly in a cold place to become stiff.
