Probably a really silly question...but, hey, I'm a newbie at this!! I have an electric smoker that has a small metal box that holds the wood chips. My question is: when the chips have burned, and turned to ash, and I need to add some new chips...I am supposed to remove the box (with an oven mitt, of course!!) and dump the ashes out, before adding the new chips, right? Otherwise, you'd end up with a full box and it would stir up a bunch of airborne ashes that would stick to the meat. Appreciate your indulging me and my newbie questions!
