Abstract: Techniques for updating the firmware of a second cooking apparatus under the control of a first cooking apparatus controlling recipe execution by the first and second cooking apparatuses in a joint cooking process. The first cooking apparatus queries an update server to check if the current firmware version of the second cooking apparatus corresponds to the latest available firmware version for providing a particular cooking function. If the latest firmware version differs from the current firmware version, the latest firmware version is downloaded to the first cooking apparatus. The downloaded latest firmware version is uploaded to the second cooking apparatus while preventing interruption of the joint cooking process. Completion of the firmware update is registered by the first cooking apparatus after receipt of a confirmation from the second cooking apparatus. The first cooking apparatus the sends the recipe instructions for performing the particular cooking function to the second cooking apparatus.
