Abstract: A method of popping popcorn in a microwave 10 having a cooking chamber 12, an energy source 14 which provides energy 42 to the cooking chamber 12, a humidity sensor 60, and a microphone sensor 16, includes the steps of placing a plurality of popcorn kernels 40 in the cooking chamber 12. The energy source 14 is operated during a popcorn popping cycle. Popping sounds generated when the popcorn kernels 40 are popped are detected, as is the humidity level in the cooking chamber 12. The energy source 14 is directed to stop operating when the popping sound and the humidity level satisfy one or more end status indicators. The current disclosure also includes a microwave 10 for carrying out the above described process.
