A method of steam cleaning a roaster bowl, such as one used in a roasting/glazing apparatus, in which an electronic technique is employed to determine, during cleaning, whether water is boiling within the roaster bowl. The method entails adding water into a roaster bowl having sugar adhered thereto and placing a cover on top of the roaster bowl. A steam vent is formed between the cover and the roaster bowl. The method further comprises heating the roaster bowl and then electronically determining whether the water within the roaster bowl has reached a boiling point (i.e., is boiling). After electronically determining that the water is boiling, the water remains boiling for an amount of time sufficient to cause the internal surface of the roaster bowl and the cover to be properly steam cleaned. The water in the roaster bowl (with sugar dissolved therein) is then poured out.
