Some concern has been expressed that opening the oven door to spritz the
interior, or to deposit some ice cubes in it, will lower the oven
temperature and therefore should be avoided.
The steel oven walls and the large volume of air in the oven retain a great
deal of heat so it isnt likely that the few seconds needed would seriously
affect the oven temperature.
If the oven is gas fired, you might be able to check this out: on some
ovens you can hear the thermostatically controlled burner re-igniting
itself when the temperature drops. If you hear it kick in, then the
temperature has dropped a bit. But does it matter?
