Alright i'm going to attempt my first cheese smoke using the can and soldering iron method. it seems like the best for me from all my research. i have a chargrill pro and it is currently sitting in the hot july sun. should i wait untill dusk or night time to do my smoking?? also i have read about 100 different timelines for smoking the cheese. anything from 1/2 hr. to 3 1/2 hours. what is best and how do you know it's done? also should i use ice no matter what??...Thanks guys
