cooled ball becomes harder. The most
concentrated syrups make a cracking sound as
they turn into hard, brittle threads. Each of
these stages indicates a particular temperature
range and suitability for a particular kind of
candy (see box below).
Syrup Boiling Points Depend on Sugar
Concentration
The boiling point of a sugar solution
increases as the concentration of sugar
increases. This graph shows the
relationship between boiling point and
sugar concentration at sea level.The Heating Rate Accelerates During
Cooking As we cook a sugar syrup, most of
