Yes I've read other threads but I am wondering if there is any new wisdom?
My questions are:
1) What temp should I smoke it at (it maxes at 275F)
2) What wood
3) Should I inject it with juices i.e. MSG+Spices
3a) If So then what juices beyond what I provided above
4) Should I TX cruch it if I only have 12 hours?
5) Where to place the temp probe?
6) Why smoke a brisket instead of a whole chicken or ribs?
I'm sure you'll get many different answers but here is mine based in what you want to do and the TIME you have.
1. 275F AND make sure your brisket is no bigger than about 9 pounds after trimmed
2. 100% Mesquite. I don't think anything for beef would beat it, but if you don't have Mesquite go Oak and then move on down the line to whatever you have if you don't have oak.
3. No. I prefer just seasoning, a Brisket can handle not being babied too much. I go SPOG, many just go SP
4. YES. You are hurting for time so I say crutch it at about 160F. A better approach for time would be to simply start 5-6 hours earlier than you plan to start it now. You can always double wrap in foil, wrap in 3 bath towels and rest it on the counter with no issue for 4-5 hours if you happen to end that early, which on your first attempt I'm almost positive you will not finish with as much time as you think :)
5. Place the temp probe in the Flat. Place it in the center most and thickest portion of the flat. Flat, flat, flat!
6. Brisket to me is the king of smoked BBQ meats. When done well it is absolutely amazing! Brisket is not a beginner cut though. Brisket will punish you if you don't prepare well for the meat alone. If you don't have good control or management of your heat, your smoke, and or your time management then a Brisket will show no mercy.
A brisket alone needs to be trimmed well to avoid burnt up pieces vs properly cooked pieces, probed well to know when to start checking for doneness (tenderness), is done when it says it is done (tender), will stall on you and not care about your time tables, will be larger than what you may be used to handling, and can/will teach you something new with every attempt.
Continue prepping well and you can go into it without much fear at all. Again, I recommend you plan your smoke to END with a
minimum of 5 hours before you plan to serve. The MES may not even hit a 275F temp with such a large cut of meat in it. At 275F go ahead and estimate 1 hour per pound and pray your MES actually hits 275F, the MES probes are notoriously off.
If you have a cooler I bet you can finish 7-8 hours before serving and wrapping with foil and 3 towels and then shoving into a cooler would proabably keep it steaming hot the entire time.
Best of luck and continue to prep on your time table in addition to the other questions you've asked :)
