T.M.
Salt and pepper the heck out of them and roast them low and slow in the oven tightly covered. I brown mine first in a little oil in a dutch oven, add some liquid (I usually use chicken broth or vegetable broth, I like that better than beef broth, about a cup or so should do ya), throw in some chunky cut carrots and some onion quarters, cover and roast until tender @ 275.. If you cook them TOO long they will be hard to chew. Roasting beef is sort of a science, too short and it's tough, too long and it's tender but chewy. You want to reach that melt in your mouth texture and 3 hours is sort of my rule of thumb for 2.5 lbs of meat, 4 hours for 3 to 4 lbs of meat.
Short ribs render a lot of fat, you can make some great gravy, or use the drippings as an au jois (sp)....
