up  with    a   steak   that’s  charred on  the outside
and cold    at  the center.
The key to  grilling    and broiling    is  to
position    the food    far enough  from    the heat
source  to  match   the browning    rate    with    the
inner   conduction  rate,   or  to  brown   the surface
well    with    intense heat,   and then    move    the food
to  finish  cooking through with    a   more    distant
or  weaker  heat    source. This    might   be  a   spot    on
the grill   with    fewer   coals   below,  or  a
moderate    oven.
Induction   Cooking
An   innovative  version     of  heating     with
electromagnetic  radiation   is  induction
heating.    It’s    an  alternative to  the stovetop
burner  or  electrical  element,    and heats   the
pot  that    then    heats   the     food.   In  induction
heating,     the     heating     element,    under   a
ceramic  cook-top    surface,    is  a   wire    coil
through  which   a   rapidly     alternating
electrical   current     flows   (between    25,000
