Rinse Ox Tails, then Chop into 2 inch chunks. dredge in flour, and season with salt and pepper. Pour oil in skillet, and heat. Add flour covered tails, and brown.Remove from pan, put in crock pot. Next, sauté onions, only adding a little more oil if needed.

Cook on low for 8 hours, or on high for 4 hours, until meat falls from the bone. Before serving, I like to remove and discard bones, and the bay leaf.
