I plan on smoking a pork loin on sunday with a dry rub. I will be using apple chips and water in my masterbuilt electric smoker. I don't know what the size of the loin will be because I havn't bought it yet, I'll do that tomorrow. Any idea how long it will take? Is water ok or should I put some apple juice in there with it? Any help will be appreciated, cause I am very new to this. Thanks in advance, Jeff
