I just purchased a 4 lb. butt, but this one (unlike any other butts I've bought previously) was tied up/held together with string. I bought this particular one figuring I could really get my rub into the thing, as it seemed looser than more typical butts. With all this in mind....can I smoke the butt with the string still attached, or should I remove it before cooking and put it on something (like a roaster) that will help keep it in place? Thanks in advance for your help.
