Jelly, Isinglass Clarified For

Put an ounce of isinglass into an enamelled saucepan with half a pint of water. Bring it slowly to a boil, then draw the pan to the side of the fire, and simmer gently for half an hour, being careful to stir the isinglass constantly, to prevent it sticking. Remove the scum as it rises, and put it on a sieve which has been moistened with boiling water. A little clear jelly may drain from it, and this may be added to the isinglass. A tea-spoonful of cold water should be put in two or three times to assist the scum in rising. When the jelly is required exceedingly transparent, a tea-spoonful of beaten white of egg may be added to the water in which the isinglass is dissolved, but when this is done, a little more isinglass should be allowed, as the white of egg has a tendency to weaken it. An ounce of isinglass is usually considered necessary for a pint of juice. Probable cost, 1s. 2d. per ounce. Sufficient, half a pint of water for an ounce of isinglass.
