“Ebullition” is based on the Latin “ēbullītiō,” meaning “bubbling up.” There are two usages for this word. The first is a metaphorical bubbling up of emotion, where feelings can spill over into a sudden outburst called an ebullition. The second usage is the physical action of bubbling or boiling. A pot of boiling water is in the process of ebullition; however, water isn’t the only substance that can boil. Many types of candy begin as sugar syrup, which is then boiled to specific temperatures in order to achieve characteristics of clarity versus cloudiness, or hardness versus chewiness. High-temperature ebullition is necessary to turn sugar syrup into hard candy, for example.
