A method for steam cooking includes introducing steam, from a steam
generator device, into a food cooking container through a supply conduit
so that at an inlet opening to the food cooking container the steam
enters tangentially to a wall of the food cooking container. The
generation of steam is controlled by a control system so as to provide a
difference between the pressure in the supply conduit and the pressure in
the interior of the food cooking container of at least 1 kPa.
