The processing unit 150 may determine the cooking state of the food using a software engine that is located in the cooking container and detects and analyzes the temperature range of the food being cooked. In addition, since the boiling point of the processing unit 150 is different depending on the type of food being cooked (e.g., water, beef bone, soybean paste stew, kimchi stew, etc.), there is a limit to determining the accurate cooking state simply by detecting the temperature of the food. , it may be possible to accurately determine the cooking state of food by analyzing the cooking temperature range.

As the object is a meal kit, the processing unit 150 may sequentially request the insertion order of a plurality of ingredients and seasonings included in the recipe information. The processing unit 150 may determine whether the request for the insertion order was successful by calculating the weight of the cooking container obtained by the weight sensor after the request for the insertion order occurs. For example, if the object is a stir-fried pork meal kit, the ingredients may include pork and vegetables, the sauce may include a sauce for stir-fried pork, the ingredients and sauce all have different weights, and the weight information is in the recipe. Information may be included. From the recipe information, there is an instruction to add vegetables, pork, and stir-fry sauce in that order, and since the weight information of the ingredients and sauce is known, it can be determined whether the request for the insertion order was successful.

As the request for input order is successful, the processing unit 150 supplies power to the induction heater 121 in the initial heating section (501 in FIG. 5) in response to the cooking temperature and heating time of the meal kit included in the recipe information. , it can be adjusted to one or more of the temperature rise section (502 in FIG. 5) and the boiling point heating section (503 in FIG. 5).

As the request for the input order succeeds, the processing unit 150 may request mixing of the plurality of input ingredients and seasonings using a cooking utensil through the user interface 130.
