I use a 12" cast iron skillet, lodge, on an electric stove. Every time I cook pancakes they are uneven all over and seem to take a longer than usual time to cook. This may be the case with other things that are cooked in it as well.
Is there something wrong with the pan? I use plenty of oil. I season it sometimes, but often will just remove the food and leave the seasoning on, instead of washing the pan.
