Hmmmm.... interesting, indeed! I can see what you guys are saying. I guess I just come from another school of thought. I am 100% self taught and did not even know that there was such a gizmo as a remote thermometer until about a year or 2 ago. As a matter of fact, I have only been using a real thermometer on my smoker for 3-4 years. I first started with a smoker that had a temp guage that said "cool--good--hot" and I cooked on it for 4 years 3 times a week while learning. I always shot for the first "o" in "good."
I still use it some times. My facination with smoking food was the beer, fire, meat and the SUPER LOW tech method of cooking. Something from the caveman days still stirs in this young feller. Hell, I love the feeling I get from having to tear the meat off a spare rib that has been cooked, but not falling off the bone. I never felt the need to check internal temp--it has cooked at a sufficient temp for 12-16 hours and natures thermometer (the bone) says "it's done." I never worried about the time it to cook the meat, I was in no hurry--as no one should be, there is NOTHING fast about good smoked food. So if opening the door costed me an extra 30 min. I did not care--or actually know. To me smoking is an art not a science. An artist uses no templates. I would like all of my barbaric, meat eating brethren to take a few to get in touch with the Art of smoking meat and not get so caught up in the Science and "exacts" of it. This means open the doors sometimes and take a pinch, trust YOUR judgement on the food not the "probe." I think that everyone should have a "cool--good--hot" temp guage to go by and just have fun with it. I'd be willing to bet that more than half of you would get better food for it. I don't even use a temp guage on my smoker at my restaurant--I just go off the factory probe and readout on the CS---yeah, it might be off but I have the "feel" of the smoker and open the door and check-in at about 12 hours. I can still out cook most---I have the customers behind me on this one. I am glad that I not very dependent on guages, etc. I like the work and personal investment(sweat equity) that goes into my food. That makes me proud.
Now what happens if your probes, guages, etc are not accurate or just quit....what do you do? Rely on yourself.
If given block/bricks and some wood and a grate and nothing else--I feel confident. Get to know what you are doing more personally--That is my suggestion---you'll be glad you did.
Sorry for the long winded reply---I am just REALLY proud of what I do and the time and EFFORT that I put into it. I feel that the BBQ community has taken alot of what I enjoy out of the process. Of course the flip side is---the new ease of making decent food has made the community larger. Can't never have too many friends!
