How long do you bake pork ribs and at what temp?

Put your oven at 375 degrees F. Dry run the ribs with a seasoning mixture of your choice. Some salt, lots of pepper. Time is a variable without knowing the amount of meat. Bake of 90 minutes and check for doneness. When the meat starts to pull way from the rib, take them out. Let stand for about 10 minutes before serving. Retain the juices for gravy if desired.
