     For example, the recipe generator provided by the application software (“APP”) comprises the following steps. In a first step the user inputs directly an ingredient of the favoured recipe. For example, the user selects a kind of meat, e.g. “beef”, “pork”, “duck” or “chicken”, from a menu “meat” or kind of vegetable from a menu “vegetables”. Further examples selectable by the user are “casserole”, “soup”, “dessert”, “bread”, “cake” and/or “cookies”. 
     In a second step the user may select further search criteria by menu items.  FIG. 4  illustrates a schematic view of an example for a page  32  of the recipe generator of the application software (“APP”) for the mobile computer device  12  according to the preferred embodiment of the present invention. Said page  32  comprises an upper menu  34  and a lower menu  36 . 
     In this example, the upper menu  34  comprises the menu items “ethnicity”, “allergies”, “season”, “course”, “technique” and “costs”. The menu items of the lower menu  36  depend on the selection in the upper menu  34 . If the user has selected the menu item “ethnicity” in the upper menu  34  for example, then the user can further select between the menu items “American”, “Chinese”, “French”, “Indian”, “Asian”, “English” and they like in the lower menu  36 . The selection of the menu item “allergies” may provide a table of typical food allergies. The selection of the menu item “season” may relate to culinary seasons. The selection of the menu item “course” allows the selection of the number of courses of the menu. The selection of the menu item “technique” provides a selection of the technical method of the cooking process, e.g., top heat, bottom heat, top and bottom heat, circulating air, full steam, half steam plus heat, quarter steam plus heat, grill and/or low temperature cooking. 
     In a next step, the recipes found by the application software are indicated on the display  18  or touch screen  18  of the mobile computer device  12 , so that the user may select one of the found recipes. The parameters of the corresponding cooking process are adjusted automatically. At last, the user may activate a start function of the cooking process by operating the keyboard  20  or touch screen  18 . 
     Additionally, the application software (“APP”) allows food pairing, wherein the main ingredients and/or main aromas of a dish are determined and groups of main ingredients and/or main aromas harmonizing with each other are defined. Said food pairing comprises the following steps. 
     After selecting a first dish and the function “food pairing” by the user, predefined further dishes are proposed by the application software (“APP”), wherein said further dishes harmonize with the first dish in view of the ingredients and/or aromas. Optionally, the user may restrict the further dishes by selecting “next course”, “prior course”, “side dish” or “main dish”. 
     Furthermore, the function “food pairing” may be supported by a database comprising appropriately configured and arranged tables of data including dishes and/or courses, wherein the main ingredients and/or main aromas of said dishes and/or courses harmonize with each other. 
     According to a further embodiment, the application software (“APP”) comprises a function “shopping list”. The function “shopping list” may be activated by the user and generates a list of ingredients required for the selected dish or dishes. The generated shopping list may be edited by the user. For example, the shopping list may by printed in hardcopy form and/or used for an online order. 
     According to another embodiment, the application software (“APP”) comprises a recipe converter. Said recipe converter allows an automatic conversion and indication of the cooking time and/or the temperature from one heating method to another, for example from a conventional heating method, e.g. top and bottom heat or circulating air, to a steam heating method. 
     Further, the application software (“APP”) may comprise a recipe recognition function. Said recipe recognition function allows the identification of signs, i.e., numbers and/or letters, in recipe data bases of different origins. For example, the recipe recognition function is able to recognize signs in a text file, e.g., PDF file, made of scanned-in hand-written documents. The recipe recognition function is provided for recognizing the ingredients, their amounts, the cooking time, the cooking temperature and/or the way of heating. Further, the recipe recognition function may provide proposals for alternative ways of heating. Optionally, the cooking parameters are converted for the alternative way of heating. 
     In particular, the application software (“APP”) may comprise a communication basis for one or more social networks. For example, the communication basis is provided for exchanging experiences and information about the recipes. There are several social networks providing a forum for themes related to cooking. Some social networks provide recipes, which may be directly or indirectly integrated into the application software (“APP”) or a corresponding data base. 
     According to another embodiment, the application software (“APP”) comprises a parameter display function for indicating information about the oven parameters. In particular, the parameter display function indicates the current way of heating, the current temperature, the elapsed time, and the remaining time. Further, the parameter display function may provide indications for necessary activities of the cooking process. Preferably, a warning before the end of the cooking duration may be indicated, for example ten minutes before the end of the cooking time. Furthermore, a warning may be indicated in order to turn-over the food stuff  11 , for example roast or poultry, by the user. Also, a warning for filling up a water tank for a steam cooker may be indicated. 
     According to a further embodiment, the application software (“APP”) comprises a multi-timer function. Said multi-timer function is applicable to a cooking process, wherein different dishes and/or courses are prepared simultaneously at the same temperature, in particular in the same oven cavity  15  of the cooking oven  14 . The different dishes and/or courses are cooked at the same temperature, but with diverse cooking durations. The cooking process is performed at relative low temperatures. The multi-timer function of the application software provides a separate timer for each dish or course. For example, the user may adjust the timer directly for the single dishes and/or courses. Then, the elapsed times and/or remaining times are indicated. Optionally, a warning signal is indicated before the end of the cooking duration. If the different dishes and/or courses shall be finished at the same time, then they have to be inserted into the oven cavity  15  at different times. In this case, a warning signal may be indicated at the points in time, when the single dishes and/or courses should be inserted into the oven cavity  15 . 
       FIG. 5  illustrates a schematic view of an example for a page  40  of the multi-timer function of the application software (“APP”) for the mobile computer device  12  according to the preferred embodiment of the present invention. The page of the multi-timer function may be represented by the display  18  or touch screen  18  of the mobile computer device  12 . In this example, the page  40  of the multi-timer function indicates remaining cooking times for three different dishes and/or courses prepared in the same oven cavity  15  at the same temperature. The area of the page  40  is subdivided into three subareas  42 ,  44  and  46 . Each subarea  42 ,  44  and  46  indicates the remaining cooking time and the name of the corresponding dish or course. In this example, a first subarea  42  indicates the dish “Pink French Lamb” and its remaining cooking time, a second subarea  44  indicates the dish “Chocolate Roulade” and its remaining cooking time, and a third subarea  46  indicates the course “Asparagus Terrine” and its remaining cooking time. 
       FIG. 6  illustrates a schematic view of an example for two domestic appliances  10 ,  110  and a mobile computer device  12  according to the present invention. 
     The mobile computer device  12  can be switched into a first connection state with the domestic appliance  10 . In the first connection state, wireless data connection is enabled by the domestic appliance  10  and the mobile computer device  12 .

     The mobile computer device  12  is switchable between the first appliance connection mode and the second appliance connection mode. 
     When the mobile computer device  12  switches between appliance connection modes, it is getting configuration data from the domestic appliance  10  or  110  which is switched into the first connection state, wherein the configuration data is saved in the memory unit of the mobile computer device  12 . 
       FIG. 7  illustrates a schematic view of an example for a domestic appliance  10  and two mobile computer devices  12  and  212  according to the present invention. The mobile computer devices  212  comprises a keyboard  220 . 
     The first mobile computer device  12  and the second mobile computer device  212  are interconnected or interconnectable via a wireless data connection with the domestic appliance  10 . 
     In a first device connection mode only the first mobile computer device  12  is in the first connection state with the domestic appliance  10 . Furthermore, in the first device connection mode, the second mobile computer device  212  is in the second connection state with the domestic appliance  10 . 
     In the second device connection mode, the first mobile computer device  12  is in the second connection state with the domestic appliance  10 . Furthermore, in the second device connection mode only the second mobile computer device  212  is in the first connection state with the domestic appliance  10 . 
     The domestic appliance  10  is switchable between first device connection mode and the second device connection mode. 
     The mobile computer device  12  comprises a display presenting a display area  180 , wherein the display area is splitted into rectangular display regions  181 , especially into rectangular app tiles, as can be seen from  FIG. 6 . 
     Each display region  181  comprises a container for displaying data. The mobile computer device  12  receives configuration data from the domestic appliance  10 . The size and the position of the display regions as well as the data to be displayed in the containers can be adapted based on the configuration data. 
     The configuration data is determined by the domestic appliance  10  and/or the behaviour of the user of the domestic appliance  10 . 
     According to another embodiment, the application software (“APP”) comprises an “intuitive display function” for indicating the status of the cooking process. For example, in the beginning of the cooking process the background of the display  18  or touch screen  18  or an indicating portion of said display  18  or touch screen  18  is dark. Then a relatively small bright area on the display  18  or touch screen  18  or the indicating portion of said display  18  or touch screen  18 , respectively, is activated. During the advancing cooking process, the bright area becomes bigger. In the end of the cooking process the whole area of the display  18  or touch screen  18  or of the indicating portion of said display  18  or touch screen  18 , respectively, becomes bright. Preferably, the bright area is enhanced from left to right. In particular, a characteristic colour for the area becoming brighter is used. The “intuitive display function” allows that the status of the cooking process may be recognized clearly and from a relatively big distance. 
     According to a further embodiment, the application software (“APP”) comprises a cooking time reduction function and/or a temperature reduction function. In this case, said cooking time reduction function and temperature reduction function require the bidirectional wireless connection  22  between the cooking appliance  10  and the mobile computer device  12 , so that the cooking appliance  10  is controllable by the mobile computer device  12 . The user may reduce the cooking time and/or the temperature wirelessly via the mobile computer device  12 . There is no doubt about the safety since the energy supply is reduced. In contrast, there is doubt about the safety, if the cooking time and/or the temperature increase, since very high electric power is operated by remote control. 
     According to another embodiment, the application software (“APP”) comprises a cooking time adjusting function and/or a temperature adjusting function, wherein an increasing of the cooking time and/or the temperature is allowed. For safety reasons the cooking time and/or the temperature may be increased by a slider, which can be activated only by two fingers at the same time. This reduces the danger of an inadvertent activation of said slider. 
     According to a further embodiment, the application software (“APP”) comprises a display function of statistic parameters. For example, the energy consumption of the cooking appliance may be indicated in relation to other parameters. The energy consumption for predetermined time periods may be indicated graphically or by a table. The energy consumption may be indicated in dependence of the types of food stuff  11  of recipes. 
     According to another embodiment, the application software (“APP”) comprises an edit function. The user may input and store an own cooking recipe for his own purposes. Further, the user may present own cooking recipes in a social network, wherein photographs of the user and/or food stuff  11  may be inserted.
