Bought a 9x9 Tile at Menards yesterday.. Worker said it was as close to unglazed as they had.. Put it in Smoker this morning to season it?? No meat or anything in there, wanted to cook off any stuff on the tile? Smoker at 275. Set it right under Water pan, on top of wood chip box to eleminate the back corner Hot spot... Is this the right way to do it??
