Pull an ounce of mild white isinglass into small pieces--rinse them, and
put to them a quart of milk if the weather is hot, and three pints if it
is cold weather. Set it on a few coals, stir it constantly till the
isinglass dissolves, then sweeten it to the taste with double refined
loaf sugar, put in a small stick of cinnamon, a vanilla bean, or blade
of mace. Set it where it will boil five or six minutes, stirring it
constantly. Strain it, and fill the moulds with it--let it remain in
them till cold. The same bean will do to use several times.
