I thought I'd bring this thread back because I'm in the same position as jpeac2 was years ago. I just picked up a 11.5lb bone-in boston butt from Butcher & Larder and will be roasting it for a crowd on Saturday. I really don't want to mess it up so I'm hoping folks can chime in with advice.
I saw a recipe in Cook's calling for 5-6 hours at 325 on a v-rack (cook until 190 internal). Of course, this was for a 6-8lb. pork shoulder. About how long can I expect my (much larger) roast to take? I would prefer to leave it slice-able rather than pulled pork-able. I've looked up some recipes for pernil but few work with such a large single piece of meat. I know, too - it's done when it's done, but I'd like some sort of a ball park so I can plan accordingly. I'd rather have it done earlier rather than later since I know it can hold pretty well. Should I go with a lower oven temperature and just put it in the oven before I go to bed on Friday night?
If I had a smoker or a grill, I'd cook it that way (or a dutch oven large enough to allow me to braise this beast), but it's not in the cards for this roast. My oven will have to do.
I wasn't planning on a terribly aggressive rub - just a mixture of brown sugar, salt and pepper for 12-24 hours prior to cooking. With some of the pan drippings, I'll make a cherry/red wine sauce to go with the pork.
Anyway, everything I've been able to read suggests that the boston butt is pretty forgiving and so long as I go 'low & slow', it will be delicious. I guess my main concern is
how 'low & slow'. Like I said, I really don't want to mess this up so any feedback would be appreciated!
best,
