A few hints-
The boston butts I have seen are extremely fatty. Try a pork roast or loin that has just a little bit of fat for flavor. I cook the meat in an electric roaster- very similar to a crockpot but bigger- overnight for about 10 hrs. Try to cook it outside if possible. The vinegar cooks out and you cannot get the smell out of your house for several days. Don’t forget to save the sauce for the end- I have added it by accident at the beginning. Still good but it is good to have the sauce for dousing. I add about a tablespoon of hickory liquid smoke at the very end for a grilled flavor. Cheating, I know but it is subtle and it works.
The good thing about this is that you can keep it in a crock pot to keep it warm.
You’re set!! Let me know how it turns out.
