A method for regulating a cooking process of a cooking product in an oven of a steamer, during which the moisture in the oven coming from the cooking product is at least periodically determined over time by a moisture sensor. During a measuring phase there is no introduction of steam into the steam oven and the moisture sensor is evaluated. For a given cooking process with fixed times for the supply of steam, on the basis of the moisture sensor evaluation during the measuring phase, the end of cooking is determined. Prior to the measuring phase and during a steam phase, steam is introduced into the oven, the steam supply being terminated following the steam phase and prior to the measuring phase during a ventilating phase. During the ventilating phase the steam concentration in the oven is greatly reduced.

Steam heating used with conventional heating techniques achieves a rapid boiling point. An intelligent electronic control system which uses sensors placed at various points in the system to monitor and / or control cooking, interacts with the Internet to determine cooking steps, powers embedded electronics in vessels by RF energy, and adjusts the heating temperatures of the contents of the vessel as a function of time. A stove will provide configurable tubes with a coupling unit at their end to attach various steam wands easily moved into position that provide this steam to vessels placed on a grill. Delicate cooking of comestibles can be achieved by maintaining a controlled temperature or cycling the temperature to maximize cooking without losing significant nutrients of the comestibles. Small coupling holes introduce steam at the bottom surface of a vessel to efficiently cook comestibles. The coupling holes have a radius which stratifies the Young-Laplace equation.

A cooking method using an automatic pressure double boiler is provided. The cooking method can prevent steam containing the medicinal or nutritive components in the medicine or health food from leaking out of the cooking pot, and thus keep the medicinal or nutritive effect of the medicine or health food, compared with conventional cooking methods, such as baking with fire, boiling with water, frying with oil, steaming, etc. The cooking method does not allow the boiled water or steam to enter the inner cooking pot, thereby acquiring pure medicinal or nutritive components from the medicine or health food. Since the cooking method heats the medicine or food with the energy of the steam from the boiled water, not direct or conducted heat energy from an electric heater, it cannot burn the medicine or food although it heats it to extract the pure medicinal or nutritive components and condenses them.
