Hot Air and Walls:
Oven    “Roasting”
In  contrast    to  the grill,  the oven    is  an  indirect
and more    uniform means   of  cooking.    The
primary heat    source, whether flame,  coil,   or
coal,   heats   the oven,   and the oven    then    heats
the food    from    all sides,  by  means   of
convection  currents    of  hot air and infrared
radiation   from    the oven    walls   (p. 784).   Oven
heating is  a   relatively  slow    method, well
suited  to  large   cuts    of  meat    that    take    time    to
heat    through.    Its efficiency  is  especially
influenced  by  the cooking temperature,    which
can be  anything    from    200 up  to  500ºF/95–
260ºC   and above.  Cooking times   range   from
60  to  10  (or fewer)  minutes per pound/500
gm.
