I had purchased a cryovac of 2 boneless pork shoulders from my local Costco. One of the shoulders weighed in at 8.5lbs and the other at 6.5lbs. I put the big boy on at 6:30pm and waited 2.5 hours and put the small on at about 9pm. I took each off about 11:30 and placed them in tin foil then wrapped in towels and put them in a cooler. They stayed plenty warm until 2pm when I started pulling them. The rub I used was a basic spice rub of garlic powder, kosher salt, cumin, and chili powder since the pork was used in tacos. I served the pork with cilantro, onions, salsa, guac, sour cream, etc. It was a great hit!
I tended the fire to ensure it was the right temperature a few times during the night, but mostly I checked when one of my kids woke up etc. I am hoping for my bday in august I get a temp controller, lol.
Everyone at the party loved it and I can totally see why Green Eggs sell themselves; 3-4 people at the party asked me where to get one. If I was a local dealer I would definitely be doing demonstration cooks.
