Not as much brown sugar as you would use for a pork shoulder. Then to it add black pepper, cayenne pepper, white pepper, garlic powder, onion powder, chile powder, paprika, dried thyme, and dried oregano. I put the spices into a spice mill/coffee grinder that I just use for spices and hot peppers. I pulse it several times to get the spices very fine, then incorporate them into the brown sugar.
You can slather on a dijon mustard, worcestershire sauce, crushed beef bouillion cubes or powder before you put on the rub if you like.
To baste I melt 2 sticks of butter, then add 2 cups of beef broth and 2 cups of apple juice or cider.
When it reaches 165 I place it into a foil pan to continue the cooking. The pan catches all of those wonderful juices!!! Enjoy.
