A method and popping machine for popping different types of popcorn kernels is provided, where the different types of popcorn kernels include at least mushroom type popcorn and butterfly type popcorn. The method includes determining a selected one of the different types of popcorn kernels to be popped in a first popping cycle based upon a selection made by an operator, and then retrieving and using a first set of predetermined cooking temperature set points associated with cooking the selected one of the different types of popcorn kernels during performance of the first popping cycle. The cooking temperature set points determine several items which may include when to heat a kettle of the popping machine, when to signal an operator to take action such as loading kernels or dumping popped popcorn, and when to add sugar if a sweetened popped popcorn type is desired.

The method of claim 1, wherein each of steps (d) and (f) comprises: providing at least one of an audible alarm and an illumination of an indicator light to identify the loading or dumping action required by the operator. 3. The method of claim 1, wherein step (a) further comprises: determining, based upon a selection made by the operator at the user interface, that a sweet mode is active for the first popping cycle such that the first popped popcorn type is to include a sweetened coating, wherein the sweet mode further requires addition of sugar during the first popping cycle to produce the sweetened coating,wherein retrieving the first set of predetermined cooking temperature set points at step (b) comprises retrieving a sweet point temperature which defines when the sugar is to be added during the first popping cycle when the sweet mode is active. 4. The method of claim 3, wherein when the sweet mode is active, the method further comprises, between steps (d) and (e): detecting when the kettle falls below the sweet point temperature as a result of cooling of the kettle caused by loading the first batch of kernels into the kettle; andalerting the operator to load the sugar into the kettle when the kettle falls below the sweet point temperature, so as to avoid burning the sugar in the kettle during the first popping cycle. 5.

The method of claim 5, further comprising: determining, based upon a selection made by the operator at the user interface during the initial power up of the popping machine, whether an offset calibration mode is activated;detecting a current operating mode of the popping machine based on the selected one of the different types of popcorn kernels; andwhen the offset calibration mode is activated: adjusting a dump offset added to the dump point temperature for the current operating mode based on input from the operator at the user interface; andadjusting a sweet offset added to the sweet point temperature for the current operating mode based on input from the operator at the user interface,wherein the dump offset and the sweet offset, respectively, enable operator adjustments to the dump point temperature and the sweet point temperature of the current operating mode based on operator preferences. 7. The method of claim 1, further comprising: performing a kettle heat routine to determine whether to supply heat energy to the kettle at about every 1 second following an initial power up of the popping machine. 8. The method of claim 7, wherein the first set of predetermined cooking temperature set points includes a cold point temperature and a coast point temperature, and wherein performing the kettle heat routine further comprises: determining whether the kettle was cold, as defined by being below the cold point temperature, at the initial power up of the popping machine; andwhen it is determined that the kettle was cold at the initial power up of the popping machine: heating the kettle to the coast point temperature; andturning off heat energy applied to the kettle when the kettle reaches the coast point temperature to allow a continued rise of kettle temperature to about the load point temperature, so as to minimize overshoot beyond the load point temperature. 9. The method of claim 7, wherein the first set of predetermined cooking temperature set points includes a cold point temperature and a set point temperature, and wherein performing the kettle heat routine further comprises: determining whether the kettle was cold, as defined by being below the cold point temperature, at the initial power up of the popping machine; andwhen it is determined that the kettle was not cold at the initial power up of the popping machine: turning on heat energy applied to the kettle when the kettle is below the set point temperature; andturning off heat energy applied to the kettle when the kettle is above the set point temperature, thereby maintaining the kettle around the set point temperature. 10. The method of claim 1, further comprising: performing an alarm routine to determine whether any alarms for the operator should be activated or deactivated at about every 1 second following an initial power up of the popping machine. 11. The method of claim 10, wherein performing the alarm routine further comprises: determining whether the popping machine is in a load alarm mode or a dump alarm mode;when the popping machine is in the load alarm mode, activating a load alarm to alert the operator to load the first batch of kernels into the kettle if the kettle is above the load point temperature, and then deactivating the load alarm when the kettle falls 15° F. below the load point temperature; andwhen the popping machine is in the dump alarm mode, activating a dump alarm to alert the operator to dump popped popcorn from the kettle if the kettle is above the dump point temperature, and then deactivating the dump alarm after 10 seconds have passed following activation of the dump alarm,wherein each of the load alarm and the dump alarm includes at least one of an audible alarm and illumination of an indicator light on the user interface. 12.
