A high altitude oven comprising:

• an oven assembly having a sealable baking compartment;
• and
• a baking compartment pressurization assembly in communication with said sealable baking compartment, said baking compartment pressurization assembly being operative for establishing and maintaining constant sea level pressure within said sealable baking compartment regardless of an elevation above sea level at which said oven is physically located;
• said baking compartment pressurization assembly including a user setable pressure regulator connected between a compressed nitrogen tank and an inlet end of a high pressure hose;
• said high pressure hose having an outlet end in connection with said sealable baking compartment;
• said sealable baking compartment being accessible through an oven door of said oven assembly, said oven assembly having a pressusre sealing gasket and an oven door locking mechanism for locking the oven door in a closed position to seal said sealable baking compartment;
• said user setable pressure regulator comprising adjustment means and associated elevation indication markings for permitting a user to set the elevation above sea level at which said oven is physically located, said pressure regulator being responsive to an elevation setting thereof by the user for admitting nitrogen from said compressed nitrogen tank into said sealable baking compartment for establishing and maintaining constant sea level pressure within said sealable baking compartment.
