Cooking beef roast in oven, needs to take 10 hours.

Ok, I got a 4 1/2 lb. boneless rump roast on sale…looks nicely marbled, one side is the coating of fat layer.

Thinking about just scoring the fat layer, placing it up, and throwing it in the oven on 200 all day.

If you can’t tell, the art and science of roasts escapes me.
