You have to use some common sense and your own taste when using MM's book. I like his rub recipe. His comp brisket and pork butt recipe differs slightly from the recipe in his book. But, either way, use your own sense of taste with them. I have a later version of his book and many of the salt issues have been addressed in it. But, I still use my own taste when following his recipes.
