An oven includes a food chamber with an access door which houses a water evaporator chamber in fluid communication with the food chamber. By sensing the temperature of the water in the evaporator and the dry bulb temperature within the food chamber and by controlling a dry heat source that heats the air and a wet heat source that heats the water, the cook can control both the final food temperature and the degree of browning of the food.

1. An oven for cooking food, comprising: a housing defining a food chamber; an access door to said food chamber, said access door defining an evaporator and defining an opening which puts said evaporator in fluid communication with said food chamber when the access door is closed; a first heat source, located in said evaporator; a first temperature sensor, which senses the temperature in said water evaporator; a second heat source, located in said food chamber; a second temperature sensor, which senses the temperature in said food chamber; first and second user inputs for setting the desired food temperature and the desired degree of browning; and a controller, which receives signals from said first and second temperature sensors and from said first and second user inputs, and which controls said first and second heat sources to reach the desired food temperature and the desired degree of browning. 2. An oven as recited in claim 1, and further comprising: an air sparger which injects air into said evaporator. 3. An oven as recited in claim 1, wherein said opening also serves as a water fill port. 4. An oven as recited in claim 3, wherein said access door has an inner wall and an outer wall, wherein said inner wall defines said water fill port opening, and said outer wall defines a water drain port. 5. An oven as recited in claim 4, wherein said water drain port is accessible through said water fill port. 6. An oven as recited in claim 1, wherein said controller also provides for periodically raising the temperature in said evaporator to the boiling point of water. 7. An oven as recited in claim 1, wherein said access door is mounted to said housing so as to pivot relative to said housing about a horizontal axis. 8. An oven, comprising: a housing defining a food chamber; a door pivotably mounted to said housing and providing access to said food chamber, said door having an outer wall and an inner wall and defining a evaporator, wherein said inner wall defines a fill port and said outer wall defines a drain port for said evaporator; a first heat source, located in said evaporator; a first temperature sensor, which senses the temperature in said evaporator; a second heat source, located in said food chamber; a second temperature sensor, which senses the temperature in said food chamber; first and second user inputs for setting the desired food temperature and the desired degree of browning; a controller, which receives signals from said first and second temperature sensors and from said first and second user inputs, and which controls said first and second heat sources to reach the desired food temperature and the desired degree of browning; and an air sparger which injects air into said evaporator. 9. An oven as recited in claim 8, wherein said drain port is substantially opposite said fill port, thereby making said drain port readily accessible from said fill port. 10. A method for cooking food, comprising the steps of: inserting food into an oven chamber which has an access door; inserting water into a evaporator defined in said access door, wherein said evaporator is in fluid communication with said oven chamber when said access door is closed; closing the access door; and controlling a first heater in the evaporator and a second heater in the food chamber to control the food temperature and the degree of browning of the food.
