• a user input for programming the recipe, the user input being configured for receiving at least one parameter for controlling at least one of the food preparation environment control devices, the at least one parameter defining an operational state of the at least one food preparation environment control device, and
• a graphical display operatively connected to the user input and configured to, before execution of the programmed recipe, display as a graph representations of operational states of the multiple food preparation environment control devices with respect to time according to the programmed recipe.
