Steak should to be cooked when you want to eat it and not before. It should also be given all the time and attention it needs. But really it doesn't need that long, 15 minutes max and you have yourself a beautiful steak. The recipe below gives the times for a rare-medium steak. You can adjust this depending on how well done you like your meat. For a perfect steak make sure the pan is hot and that the the rump steaks are seasoned and rubbed with oil. Once in the pan try not to touch the steaks or move around until you are ready to turn. Check how well-done they are by pushing on the meat with your finger, the firmer the meat the more cooked in the middle. Always remember to rest the steaks for at least 5 minutes before slicing and serving.
