I've smoked a pork shoulder last summer and it turned out incredible. One of the best pieces of meat I've cooked in the smoker before. I'm comfortable with temperatures, injecting, seasoning, when to wrap, and when to pull. I have not cooked a 4 pound piece of pork before. Approximately at 225-250 how long will this thing take to cook? Keep in mind I'm using a WSM 18.5" smoker so it will sit over direct heat. Ultimately the temperature of the meat will the guide cook time. I'm trying to get this thing done as close to 8pm as possible.
Side question as well: Should I leave the pork in the pan for the entire cook and only cover the pan when the internal temp hits 160 or put it right on the grate until 160? I feel like last summer I left it in the pan. I get nervous I won't get a good bark if I don't put it right on the grate.
1 cup 1/2 apple cider vinegar, 1 cup 1/2 apple juice, 1 stick of melted butter. Covered the pan in foil and letting it sit for 12 - 18 hours.
Olive as the "glue".
Stage 1: Salt, Pepper, Garlic Powder, Onion Powder
Stage 2: Heller's BBQ seasoning (local seasoning rub - quality rich flavor), Chipotle Chili Powder, Cayenne Pepper (debating chili powder and Caynenne.....)
Thanks for any help and advice!
