Scrub the grill grate. Coat the grill grate with canola oil. Preheat a charcoal grill. Alternatively, preheat a gas grill. Check the grill before beginning.
Use a wire brush to scrub the grill grate, removing any traces of burnt on food from previous grilling sessions. Even if you cleaned your grill after using it, it is still a wise idea to clean it again, especially if it has not been used for a while. Scrubbing the grill grate also helps to remove other debris that could have gathered on it in between uses. Pour a small amount of canola oil onto a clean paper towel and rub the paper towel over the grate.  The oil creates a non-stick coating that will limit the amount of steak getting stuck to the grill as it cooks. In the absence of oil, you could also use aluminum foil. Cover the grill grate in aluminum and poke holes throughout the foil with the tines of a grilling fork. You must poke the holes in the foil so that enough heat can travel through. You should begin 20 minutes before cooking, and you need to prepare two areas of high heat and one cooler area.  Set the grill grate aside temporarily. Use a chimney starter to ignite a moderate pile of charcoal briquettes. Let them burn until they are covered in white ash. Dump the hot coals into the bottom of the grill. Use tongs with a long handle to carefully spread the coals. You should have two or three layers in one-third of the fire bed, and one or two layers in another third. The remaining third should have no coals. Return the grill grate to the grill As with the charcoal grill, begin 20 minutes before you plan on cooking. Turn all heat elements on as high as they will go. The grill must be very hot before you can add the steak.  To check a charcoal grill, hold your hand roughly 4 inches (10 cm) above the tallest flames. You should only be able to count to 1 before needing to pull your hand away. If you can tolerate the heat longer, the grill is not hot enough yet. For a gas grill, the temperature gauge needs to reach 500 degrees Fahrenheit (260 degrees Celsius) before it is ready.
