Several embodiments include a cooking instrument. The cooking instrument can include a heating system. The heating system can include one or more heating elements capable of emitting wireless energy into the cooking chamber. The cooking instrument can also include a control system. The control system can determine a heating sequence (e.g., logical instructions) to drive the heating system. The control system can then execute the heating sequence. The heating sequence can include an instruction to adjust, based on a trigger event detectable by the control system, the spectral power distribution of wireless waves emitted from a heating element in the heating system.
