I really want to try a brisket but the price of them in Charlotte is outrageous. I've been looking at "packers" at Wally world, the cheapest I've seen is $31.00. At my local Costco, I've seen "flats" for about $20.00 (and they're not huge at all). Price per pound, and if it's trimmed or untrimmed are what you need to look at. A whole packer, untrimmed should be less cost per pound than a trimmed brisket.
Here are my concerns and questions:
1- If i broke down and went with a Packer, how technical is it separating the flat from the pointer? I assume that the entire packer is made of two pieces, (i) the flat and the (ii) pointer. Is this correct? It's really not very technical...just look for the muscle grain direction to determine which muscle it is. There is a thin fat layer and membrane between the two muscles. The point muscle grain runs across the packer, while the flat muscle grain runs lengthwise the packer. The point is the thickest end of the packer, and the two muscles intersect/overlap each other with a taper in the thickness of each muscle towards the center of the packer.
Here's a few different looks at how I have separated the point/flat cuts, pre-smoked and mid-smoke...

2 - I've read that I shouldn't put my probe into the meat until after 4 hours. Exactly why is this? By not probing too early or injecting marinades, you can maintain the intact whole muscle nature of the packer. This allows for less restrictive cooking times/temps regarding the danger zone. If you probe too early for internal temps, you could force any bacteria on the surface of the meat to become imbedded deep into the muscle with the probe, where temps will remain in the danger zone longer.
3 - Is the purpose of wrapping the beef to keep it moist (as does wrapping a pork butt)? Wrapping foil will reduce cooking time, if you so choose, but also softens the bark on the surface. Foiling (and oftentimes wrapping in towels) is a standard practice to rest the meat before slicing or pulling. Resting allows the meat's natural juices to redistribute throughout the muscle for more uniform moisture content of the finished product.
4 - Squirting. What do you squirt your meat with? For ribs and butts, I usually squirt with a combination of apple juice and apple cider? Personally, I don't add liquids to the meat during the smoke. It increases cooking time by loosing heat form the smoke chamber, and also by cooling the meat's surface when the liquid contacts it. Benefits of spraying are negligible, IMHO, and may actually cause the meat to become drier at higher finished temps due to keeping the meat's surface porous allowing more internal moisture evaporation.
5 - The most important question. If I freezethe brisket, will I damage it. I find that beef gets really dry once it's been frozen and then thawed out. All flesh will have liquid purge from the muscle when it thaws, some species and cuts may purge a bit more than others, though I rarely smoke a brisket or other meats that I did not store in the freezer. What you should avoid is taking a previously frozen meat and re-freeze it without cooking or processing it in some manner. That's a double-whammy on liquid purge, and may cause a drier finished product. If you have a cut that was frozen, you can cook it, then freeze again to serve at a later date after reheating...no problem, if properly packaged for storage.
Thanks all!
