Instead of injecting I decided to marinated it. 4 cups apple cider, 4 cups water, 1 cup sugar, 1\2 cup of each, apple cider vinegar, Worcestershire sauce and salt. Put in a plastic container and added enough water to cover the butt.
Just dry rubbed it this morning. :;:smokin 1/8 cup brown sugar, 3 TBS kosher salt, 1 TBS each black pepper, chili powder, smoked paprika, 1/2 TBS each of granulated onion and garlic, cumin and dried dill weed. Slathered it with mustard before dry rub was put on.
It will go on the smoker at 6 tomorrow morning using pecan biscuits and spritzed with apple juice for around 8 hours at 225. Wrapped in foil and placed into the oven at 300 for 2 hours.
