I'm making this today... For those asking/wondering about the 190 degree recommendation, that is not a typo. 190 degrees is the magic temp at which the collagen in the meat begins to break up and melt into a god-like, oily, saucy, moist liquid that gives properly cooked pulled pork its awesomeness. It's fine if you cook it to 145 or so and enjoy it that way - it just ends up being different, more like a cut of meat that stays together. Between 150 and 190 or so is a strange period where the pork actually dries out... But if you let it go to the magic 190, even 195 or so, that's when the magic happens and it goes from dry to incredible. It can take some time - it's like the temp may go on pause for a while - but then when it begins to rise and you reach that 19 and you begin to wonder if it will ever increase again - but once you hit the 190 mark, you will have the best pork you can imagine. Keep this in mind for ALL pork shoulder recipes, really, depending on what you're going for.
