*Tri cooked = What happens around noon when Mrs Zombie asks what time I should start the smoker for the pork shoulders, and I say "Oh about 5-6 hours ago".
Cook 1: fire oven to 425 and put 3 of the 4 halves into the oven for 20 minutes, then drop temp to 300, and progressively keep dropping the temp until at 170.
Cook 2: Drop shoulder half 4 into a pressure cooker with pineapple juice and cook for 45 minutes. When done, rotate with one of the oven halves.
Cook 3: Load the grill with apple wood and finish the pork with the smoke.
