Blackberry-Bourbon Boston Butt: Best cooked low and slow in your favorite smoker at 225 Degrees. The fat inside a butt needs to break down, so insert a internal meat Thermometer, as you want your Butt to register at least 190-195 internally when done . Tender and moist when smoked correctly. Happy Smoking. These are great for Pulled pork and mixing with favorite BBQ Sauce for sandwiches.
