Caramel is partially burned sugar which has a brown color and a pleasant brown sugar flavor. Caramel is used to flavor candy and soft drinks such as Coca Cola. The word caramel also refers to a soft, chewy caramel-flavored candy made by boiling milk and sugar together.
Caramel can be made from sugar by heating it slowly to a temperature of 170 degrees Celsius. As the sugar melts and approaches this temperature, the molecules break down into other volatile compounds that give it the characteristic caramel color and flavors.
