Pan Seered To Perfection

I am in the kitchen cooking and dumped the remaining contents of a bag of noodles into a pot, only to discover it had weevils. So I turn off the burner and empty out the pot, then put new water in it. I put it back on the stove and turn on the burner. As I sit and wait for the water to boil I smell something burning. Too bad there wasn't anything in the cast iron skillet cooking.
