Abstract: 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.
