Abstract
A method of popping popcorn in a microwave having a cooking chamber, an energy source which provides energy to the cooking chamber, a humidity sensor, and a microphone sensor, includes the steps of placing a plurality of popcorn kernels in the cooking chamber. The energy source is operated during a popcorn popping cycle. Popping sounds generated when the popcorn kernels are popped are detected, as is the humidity level in the cooking chamber. The energy source 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 for carrying out the above described process.
