bulleye, this is your first post, so don't take it wrong. It's a valid question and we're always here to help.
The issue is that indeed, while they may be called a "recipe" in a book, that doesn't mean if it says "cook for two hours" you just pull it out at two hours.
You are correct in asking, because the recipe didn't say a cold smoker or a hot smoker.
Assume it's AFTER the smoker is up to temp.
But...
Check out the thread at the top of this forum "lessons for new users", I believe in there one of the things we've mentioned is to ignore those times.
Why? Because of experience. I've seen 100's of posts over the 12+ years here that people were disappointed because they followed a recipe. There are a LOT of variables. You mention one, but also is the smoker running at that time (or a little hot or a little cold) what is the weight of the meat, the thickness, the prep method, the meat is it enhanced/brined/something else.
There ARE a lot of variable.
Good news? We can help.
Instead, start a new thread, in the appropriate forum, and let's discuss what you want to cook, the specific recipe and how to tell when it''s done.
Rule #1. Keep a note book. You'll want to build on your experiences.
Rule #2. Read. There is a LOT of valuable information here, most from new users who've learned a few times and tried to share that info
Rule #.3. Have fun. Really, those bozo's above really were just trying to help, they just don't write these long winded SMOKIN' posts like I do...
