I love short ribs cooked in a crock pot. I don't bbq them, though.
I usually use 3-4 lbs of ribs, salt and pepper them and brown them well in a fry pan. I slice 2 large onions thickly, and 6-8 carrots into 2 inch pieces. Place all of the carrots and 1half of the onions in the crock pot, top with half of the ribs. Top with the rest of the onions and top with the ribs.
I add 1 tbsp of tomato paste to 2/12 cups of beef stock, a Knorrs beef bouillion cube and a little salt and pepper and 2 bay leaves.
Cover the crock pot and cook on high for one hour. Then turn to low and cook for 7-8 more hours. They are tender and delicious.
