The first part of the rule clearly defines what "pork" is and then goes on to say "pork" has to be cooked whole. It seems intentional to me. If you trim it to something that does not meet the definition of "pork" it is illegal.
When it comes down to it, I am merely trying to point out how KCBS may interpret the new rule to keep people from getting in trouble. Personally I will continue cooking my 10 pound pork butts whole.
I am curious if anyone has other substantive issues with the modified rule, beyond it allowing smaller cuts?
