Yesterday I bought what I though was 4-small Pork Shoulder Blade Boston Roast. I was planning on cooking them tonight/tomorrow, and promised 3 close friends that they could each have a butt. Upon further review, it turns out they a 2 Roasts of 9 pounds each. So now I am wondering what I should do? Cook both of the 9 pounders, and then cut them when they are done - or- Cut them both and cook all 4 smaller pieces. And if I do cut them, can you describe where to cut them? Any thoughts or suggestions?
