   I had to look up what they were. Very finely-slices apple sprinkled with   
   cinnamon that you bake. Sounds wonderful

   Four hours sounds about right to dry fruit: evaporating water is fairly   
   power-intensive. My mother used to dry fruit at a lower temp but   
   overnight, because her house had a dual meter which gave cut-rate   
   electricity from 11pm to 8am.   
      
   I'm surprised they haven't pre-dried them so that the oven time is   
   limited to the amount needed for crisping them up.

   Heating up to temperature takes more than keeping it there for the   
   remaining approx 3¾ hrs, so measure them separately.   
      
   Read your meter   
   Keep everything else on or off (ie no other changes)   
   Turn on oven and heat to 200°F (watch that light)   
   Note the time it took, and read the meter again   
   Leave the oven at 200°F for whole hour   
   Read the meter again   
      
   Now you can work out how many Kw it takes to get to 200°F /and/ how many   
   units it takes for every hour after that. Then multiply by the cost of a   
   Kw from your electricity company.   
      
   (Someone else check my logic here, please)
