smoked this butt for 21 hours. Absolutely loved it! put my mustard and Gates Spicy Rub on it, threw it in the fridge overnight. Used apple juice and water in my smoker, a mixture of Hickory and Cherry wood, and a spray of water and Fireball Cinnamon Whiskey. Would spray and add wood about every hour and a half. I have to say, this was the 4th butt I have ever smoked, and it was the best. Getting much better at smoking. Made a homemade BBQ sauce to go with it, and smoked 5 pounds of sausage. It was all so good. Can't wait to make another.
