Boston Butt holding time

You can't wrap and pull and expect it to be good 8 hours later (or longer if they're ready at 6am). As soon as you pull it, it will lose moisture.

You have to keep it food safe (above 140) for that time.

To be food safe (with that many people you need to be) you probably need to cool it off then reheat. I wouldn't try to hold pulled for that long. If it was me, I'd finish it much closer to the time and then pull it as late as you can.

That's my quick answer.

Dropping it off seems to be the problem.

What heat options do they have, they probably need to reheat.

When you drop it off they need to cool it quick then reheat.

I'm sure some others will have some ideas to help.

Thanks
If I cook and wrap, how long can I wrap before I shred and serve? It sounds like I should drop off as close to serving time as possible.

If you double foil, wrap in towels, and cooler them, they will stay hot to the touch for several hrs.

I have taken hot rib racks off the smoker, straight into foil and a cooler, insulated with towels and newspaper, and burned my fingers on the ribs three hours later.

Holding pulled pork is different, because it has to be cool enough to work with and you lose most of the heat in the process of pulling it. Unless you pull at a high temperature in about ten minutes each, you are not going to have much heat left for holding.

If they have no heating option whatsoever, I would pull into aluminum roaster pans, then heat or reheat the foil covered pans at 225 until they are warmed through, then drop those in an insulated cooler and transport. This should buy you at least an hour or two holding time prior to serving.

If they have a heating option, pull into roaster pans and foil to reheat in the oven, or glass casseroles and plastic wrap to reheat in the microwave. Either way, refrigerate and deliver cold.

If you're pulling first, listen to twofer. My suggestion works only if you pull just before eating.

Thanks for the input
I am going to put on at midnight and take out at 1:00 pm tomorrow. I will foil,wrap in towel, and place in cooler for 2 hours. Will pull at 3:00 pm
Thanks again

FTC in the smallest cooler you have and they'll stay hot for 4 to 8 hours

Followed my last plan above....
Put on at 11 pm and took off at 1 pm the following day
Wrapped in foil and beach towel
Placed in cooler and delivered
They pulled at 3 pm (I had to get back to my
Daughters soccer tournament)
I was the talk of the party! Well the Q was...
Thanks again for the help.
