I don't know what's going on, but I'll be go straight to hell if I can make a grilled cheese sammich. I have a small four burner stove, it measures about 2.5'x2.5', I have a name brand cast iron skillet, and I have the fire up at about medium. Some of the sammiches will be burned to crap at one edge and barely cooked at the other end which tells me the skillet isn't heated the same through out. What the hell can I do, a concerned Chef Wanna kill these ads? We can help!
