Cooking A Boston Butt On A Big Green Egg Why Did My Pork Roast Turn Out Like This?

Why did my pork roast turn out like this? - cooking a boston butt on a big green egg

I had pulled a Boston butt pork and usually what I read in my 13 to 9 casserole dish with glass, but only buy a larger metal baking, as it was cooking a turkey or ham I should cook for 5 hours, but the half of the onions in and started firing was 5 hours, until everything is burned very serious, inside and out to dry. .. awful ... not how we cook in general. Ive never used one of these plans forward. I cooked at 350, then left him in 325th Is it the bread?
