I've read much on these forums regarding mops, sauces, rubs, etc. In pork butt 101, there is the Vinegar Mop, and two sauces.
What I want to do is put rub on the butts, smoke them, and then sometimes apply a sauce (mop?), to add flavor. And it seems to me, after vacuum sealing and freezing, that one of the above might help to moisten the pork after thawing and heating. Or add it before sealing and freezing.
My question is: What is the difference between a mop and a sauce? Is there a difference? Is a mop something to apply to the outside of the meat before/while smoking? Or does it serve a dual purpose, ie outside mop and sauce?
Also, at the bottom of Pork Butt 101, it says to mix and heat the ingredients, is that for all three? I also notice that the "sauces" have a fair amount more ingredients. Thanks for help.
