I have 2, 10 lb pork shoulder roasts that need to be roasted in my oven and done by noon. What is my start time? I certainly don't want to cook them as if a 20 lb roast, but don't feel certain that only cooking as a 10 ob roast is sufficient. Any help is greatly appreciated.
Pork shoulders should be cooked low and slow, which is great because it gives you quite a bit of wiggle room. I'd recommend 12 hours at 275 with a lid on each roasting pan. I'd also recommend searing them on high heat before roasting in the oven.
Here's some anecdotal evidence to back me up:http://eggheadforum.com/discussion/1143833/how-long-to-cook-two-10-pound-pork-butt
