12-Hour Smoked BBQ Pork Tenderloin with Apple Juice Wrap

A deeply smoky and tender pork roast that showcases the power of low and slow cooking. The mustard base helps the BBQ spice blend adhere while adding tangy depth, and the apple juice wrap keeps the meat incredibly moist during the long smoke. This impressive centerpiece feeds a crowd and delivers restaurant-quality barbecue at home. The two-stage smoking process creates a perfect bark while ensuring fork-tender results that practically fall apart. Ideal for weekend gatherings, holidays, or any time you want to impress with authentic BBQ flavors.
