Of course, to make an extremely accurate test of this
kind, it would be necessary always to have the water at the same
temperature, a condition that can be determined only by testing the
temperature, but such accuracy is not usually required.
If the thermometer is used, all that need be done is to insert it into
the candy and allow it to remain there until the temperature is
registered. In case it does not reach the right temperature the first
time, keep the mixture boiling until it registers the temperature that
is decided on as the correct one.
59. To test the mixture by the water method, allow it to boil almost
long enough to be done, and then try it at close intervals when it is
nearing the end of the boiling. Dip a little of the sirup into a spoon
and drop it slowly into a cup containing a little water. Not much sirup
is needed for the test, a few drops being sufficient. Gather the drops
together with the tips of the fingers and judge from the ball that forms
whether the candy has boiled sufficiently or not. If the ball is not of
the right consistency, boil the candy a little longer, and test again.
