To grill a perfect steak, you need a little equipment. Here is how we do it. First season the steak. Next vacuum seal it. Fill a tub with water and add an immersion circulator. Set the temperature to 125F (for medium rare). Put the steak in its bag into the water making sure it is totally submerged. We clip ours to one of the sides. Once the water comes up to temperature, let it stay in the bath for at least 1 1/2 hours but it can go longer if you need some extra time. When the time is almost up heat up your grill for 10 minutes (gas grill.)  Take the steak out of the bag and put in on the grill for two to two and a half minutes on each side. Result-perfectly cooked medium rare steak with nice grill marks on both sides.
