Call it the money muscle or the neck muscle or the top of the pork butt or whatever, but it's quite delicious.
Next time you BBQ a pork butt, remove the MM 1st, rub it and cook it for 3 hours at about 275*-290* for 3 hours. Then, wrap it in butcher paper and cook it about another hour until it reaches about 198* internal. Remove from smoker, let it rest for about 30 minutes then slice it into medallions. No sauce necessary, I assure you.
