Audrey,
Check out my post:
Pork Ribs 101It should help with a few questions.
Also, I moved your posts and combined them. We try to use the other forum for smoker "specific" questions, about how to operate it, etc.
Over her in this for is the "how to" area.
We'll help you out.
You can achieve "fall off the bone" without ordering out or without using foil. If they're not doing that, you're not cooking them long enough.
First, don't go with the instructions. They've been discussed here a number of times and they're actually an old way of doing things.
As far as getting fall off the bone, remember my motto:
It's Done when It's DoneWhat that means is, that you have to learn to let the ribs tell you when they're done. You can't go on a specific time, temp. Those are broad guides, you'll have to learn.
The best way, is to look at the bones. You'll see that the meat pulls away from the ends as the time increases.
Next, just grab a rib (it will be hot) and just give it a twist. does it pull out?
Also, you can take the ribs out and handle them. That's why I keep some good rubber insulated gloves handy.
Basically, learn to look and feel and pull them when they're ready, not based on the time.
There is such variation in size and type of ribs, the only times we can give you are general in nature.
I can put 6 racks of ribs in and pull them all out at different times because of many variations.
Hope that helps.
