My first time using the smoker today. I'm going to do a Boston Butt 4.5lbs @225-245 for 6hrs. I read some awesome helpful tips on preseason and rubs. My quesion though is kinda ridiculous. 1. To soak or not to soak? I'm using Applewood chips. 2. and this is the ridiculous one....how often do you add? I'm assuing when you stop seeing smoke coming out of the top vent? Do I have to stand there or is a general rule one cup per hour thing? Really excited I found this site!!! Everyone has been super informative and very helpful. Thanks in advane for the response. Getting really excited for my first smoke ever!
