A cooker 10 comprises an un-pressurized cooking volume 16 enclosed between a cooker body 12 and a removable cooker lid 14. A processor 30 employs a temperature sensor 26 to control the temperature attained by the cooker body 14 from heat generated by a heating element 34 (46). A steam sensor 28 detects steam expelled from the cooking volume 16. Whenever the cooking volume is open, detected by the absence of expelled steam, the controller 30 causes the temperature of the cooker body to become elevated above cooking temperature to compensate for the cooling effect of the absence of the cooker lid 14. The controller 30 obtains details of the content of food pack where items can have different cooking times. The controller 30 reduces the body 12 temperature to a cooking temperature when a first food item is added, starts timer for the cooking time of that item, and prompts the user to add subsequent food items as each food item 18 becomes due for addition to the cooking process. The cooker 10 can be driven by gas or electricity. The content of food packs are selected by participants providing food item preferences in response to poll and food packs bearing regional preferences being provided in the areas or regions of polled individuals. |
