The first process is _clarifying_, which is done thus. Break the
white of an egg into a preserving pan; put to it 4 quarts of water,
and beat it with a whisk to a froth. Then put in 12 pounds of sugar,
mix all together, and set it over the fire. When it boils put in a
little cold water, and proceed as often as necessary, till the scum
rises thick on the top. Then remove it from the fire, and when it is
settled, take off the scum, and pass it through a straining bag. If
the sugar should not appear very fine, boil it again before straining
it.
