Thanks for all the help on my pork butt, this time I am seeking advice a day in advance instead of mid cook when my temperature fails! Anyways I have my first rack of ribs baby back 4.23lbs I have putt my rub on as well as injected the ribs with a secret injection. Any tips or advice? Temps to cook at and how long? I want the meat to fall right off the bone like my pork butt did. Thanks guys.
