I have my pork ribs and the barbecue sauce. I want to roast them in the oven for noon. I plan to cut them into 2 ribs sections first. I plan to brown them and then place them in the sauce in the oven at 350. If I put them in at 9:30 should I lay them all out flat on an cookie sheet or covered in a roasting pan and last 1/2 hour spread them out to crisp on a cookie sheet? Will 2 1/2 hrs be too long and meat fall off? I plan to take them to a picnic and I want them to turn out. HELP!
