Interaction step 36 (see Fig. 10). The control unit 14 outputs via the output unit 12 an indication regarding a transition from a first recipe step to a second recipe step (see Fig. 5). In the interaction step 36, the control unit 14 outputs an operating request via the output unit 12. The control unit 14 requests the operator to turn over food 16. The operating request has the turning of food 16.

In a confirmation step 38, the control unit 14 requests the operator to confirm that an action requested by the operation request has been confirmed (refer to FIGS. 6 and 10). The control unit 14 requests the operator via the output unit 12 to confirm completion of the recipe step. The operator confirms the completion of the recipe step by an operator input by means of the control unit 26, should the desired result correspond to an achieved result. Otherwise, the operator changes by means of an operating input by means of the operating unit 26 at least one operating parameter of at least one recipe step of the selected recipe, in particular the recipe step, such as a time duration and / or a set temperature. The control unit 14 executes the recipe step in accordance with the specifications as a function of the operating input by means of the operating unit 26.

In response to a confirmation of completion of the recipe step, the control unit 14 starts a checking step 40 (see Fig. 10). The control unit 14 checks in the test step 40 whether the selected recipe has ended. If the control unit 14 determines in the checking step 40 that at least one further recipe step of the selected recipe is still to be carried out, the control unit 14 repeats a cycle in the form of the cooking step 34, the interaction step 36 and the confirming step 38 (see FIGS 10). If an action by an operator is required before a start of the cycle, the control unit 14 outputs via the output unit 12

Alternatively or additionally, the action could be, for example, a treatment of a food, such as in particular a setting up and / or hanging and / or turning and / or adding food and / or ingredients.

If the control unit 14 determines in the checking step 40 that all the recipe steps of the selected recipe have already been carried out, the control unit 14 terminates a performance of the selected recipe in a final step 42 (see Figures 9 and 10). In the final step 42, the control unit 14 automatically deactivates activated heating elements after completion of the selected recipe. The control unit 14 outputs in the final step 42 via the output unit 12 information to the operator regarding the completion of the selected recipe. In the final step, the control unit could issue an operator request via the output unit, in particular for confirmation of the termination of the selected recipe.

In the method for operating the hob device 10, a catalog of recipes for selection is output by the control unit 14 via the output unit 12. An operator is guided through a selected recipe in response to an operator input.

The control unit 14 has a memory unit (not shown). In the

Memory unit of the control unit 14 is stored a plurality of recipes. The recipes stored in the storage unit together form the catalog of recipes. The recipes stored in the storage unit are predefined. The control unit 14 stores further recipes in the memory unit as a function of an operating input by means of the operating unit 26. In response to an operator input by means of the operating unit 26, the control unit 14 changes already in the

Memory stored prescriptions, in particular on predefined and / or stored in response to a previous operator input recipes. The

Control unit 14 stores the changes made to the recipe by the operation input by means of the operation unit in the storage unit. For example, the control unit could add another recipe, which could be formed by the changed recipe. Alternatively, the controller could replace the existing recipe with the changed recipe. The control unit 14 changes depending on a Operating input by means of the control unit 26 at least one recipe from the catalog of recipes.
