I like to keep it on the dry side so no mould . A few days before I want to smoke it I put a few carrot slices in a baggy with it and watch it close. When you slice the carrot dry the slices with a paper towel so they are not wet. Some use apple and other fruit but carrots will leave no taste. It just depends on how much smoke and how much carrots. I also heard some fresh leaves put in with it will help.
