You fixin to get real bizzy soon!
Heres a lil hint, pull the foil open a bit at one end of the butt, and drain it into a measuring cup or something you can see through, glass or clear plastic. After you drain it, then set in down still in the foil and pull out the bone, should come out clean. Now take tongs or big fork and break it into 3-5 pieces, and seperate. then start working on one piece at a time as they cool. It will be very hot in the center of those pieces for 10-15 minutes. While you do this put that juice in the freezer. when you are all done pulling and the meat is still warm, take that juice out and skim the fat offf the top, it will look like wax, then pour the remaining darker juice back onto the pulled meat and mix it up! Bag it an let sit on the counter while ya get ready for the next round. If you are gonna add a finishing sauce, add it to the meat before ya bag it.
When the bag finally cools down, then put it in the fridge!
Hope this helps!
