Modular steam cooking system for a home cooking appliance

A modular steam production system for a home cooking appliance, the system comprising:

• a steam generating unit having a heating element for generating steam from water;
• a water reservoir for storing a quantity of the water, the water reservoir being fluidly coupled to the steam generating unit;
• a controlled water release system including a valve movable between a closed position and an open position to control a release of the water from the water reservoir into the steam generating unit and thereby controlling a volume of steam generated by the steam generating unit;
• a mechanical connection configured to engage a corresponding mechanical connection on the home cooking appliance to provide motive power to the controlled water release system to actuate an opening and closing of the valve, and
• at least one vent fluidly connecting a steam cavity of the steam generating unit to an exterior of the modular steam production system,
• wherein an exterior surface of the water reservoir facing the steam cavity is tapered to guide the generated steam to the at least one vent.
