Tom, thanks for the help,
I was suspect from the start with that brisker. Sales person told me it was choice. I asked where on the package it was marked that way. He said that supplier always supplies choice meat. I still am suspect cause all the other meat was marked "select" in the refer reach-ins by the same packer.
Regarding the AQ probe: It fell right out of the brisket. When I touched the product in various places, it was soft (like a sponge) at the point and the flat had a resistance of pushing on foam rubber. Also felt like a cooked pulled-pork-but.
Did not check with an instant read on any part of the brisket.
Only cut slices when every body was ready. Cut slices only sat on a serving plate for five minutes prior to being on someone's plate.
When cutting up the point. It was plenty moist, but too fatty to serve. Only some pieces could be pulled from the fat and was served over sliced bread.
Maybe I should of stopped it at 180 * and check it out. I that point I could of probed it with an instant read in a few places, fork-checked. Made a plan of action on how to get the required results with possibly foiling for additional hour?
