Marinate eye of round roast in buttermilk, covered overnight in refrigerator. Next day, wipe meat dry with a paper towel, and season with salt and pepper; brown meat in Dutch oven. Add onions, carrots, celery, and 1 cup of buttermilk from the marinade, to meat. Cover Dutch oven, and bake 2 1/2 to 3 hours at 300 degrees, or until meat is tender. Slice beef against the grain, and serve slices with gravy. Will serve 4 people. Servie with noodles, mashed or boiled potatoes.

Dave's Tip: Before marinating, poke several holes in the meat with a sharp knife. This is the best way to get the buttermilk deep into the roast!
