In lieu of fully re-seasoning your grill with each use, there are simple steps you can take to maintain and care for the condition of your grates. After each use, take a moment to run the wire brush quickly over the grates to clear away any immediate drippings. The heat in this case is helpful for removal when in smaller portions and in the moment. In the same step as above, use a pair of kitchen tongs and a paper towel to coat a layer of high heat oil over the cleaned grates before closing the grill top to cool.
The first thing you have to do is get it home safely. (I laughed and laughed when I heard this story). Apparently there is a vacant lot on the corner right next to the local WalMart. The employees at WalMart call this lot the Grill Eater Lot. There are several smashed up grills that ended up dumped in that vacant lot as their owners took the corner too fast and lost the grill out of the back of their pickup trucks (I totally need to drive over there and get a picture). So – a tip for the new grill owner – tie it down before you leave the store :-).
If you're salting right before cooking: Again, let the steaks sit at room temperature for 30 minutes, sprinkle both sides (and the edges) generously with Kosher salt and freshly ground black pepper. Press the salt crystals and pepper granules into the meat. We like to brush our steaks with a little bit of clarified butter right before we grill them. You could use a refined high-heat oil or a mixture of oil and clarified butter.
Clean out the burners and venturi tubes. The venturi tubes are the pipes that go out from the burners and connect to the grill control valves. These tubes allow the air and gas to mix together, altering the intensity of the flame. Remove the burners and venturi tubes, and place a hose head at one end of the tube. Turn the water on to clear out any debris or insects that could have gotten inside.
Cast iron grill grates conduct heat quickly and evenly, cooking and searing meat for that distinctive charbroiled flavor. But to achieve those delicious results, cast iron grill grates need proper seasoning and regular care. Seasoning cast iron grill grates when they're new keeps your food from sticking and can prevent rust to make the grates last longer. Cooking on cast iron helps to create a smooth, non-stick surface to minimize seasoning needs in the future. Cast iron is porous, and as meat cooks, fats and oils soak into the pores where they harden.
With the grates removed, brush down the inside to clear out any loose particles that have collected in the bottom and around the sides. Scrape off any large peeling flakes of carbon and grease and if yours is a charcoal grill, empty the ash catcher. Don’t forget to clean the drip pan and grease cup in warm soapy water and line them with aluminum foil so they’ll be easier to clean next time.
Transfer the steaks to cooling racks with a sheet pan or cookie sheet underneath, cover the whole tray with plastic wrap and stick them in the fridge. Take them out about 30 minutes before cooking, pat them dry again with paper towels (because the salt will pull out some juices), season with freshly ground black pepper (press the pepper into the meat as you did with the salt) and then grill as you normally would. We'll talk more about black pepper in a moment. As for patting the steaks dry, a dry steak will form a browner crust when it's cooked.
Now it’s time for propane flames to meet with forged cold steel. Turn up the heat and sit back while you watch the griddle plate blacken. The griddle will billow with smoke. That’s called “smoke point” and it takes about 30 minutes for your Blackstone to get there. So relax, grab a seat, and watch the smoke fly by. When all the smoke’s gone, you can turn off the griddle.
Clean the cook box. Remove the cooking grates and use a stainless steel cook brush to brush all the excess grease and debris from inside of the grill into the collecting bottom tray. Then, remove the bottom tray and throw out the collected grease and debris. Some of the debris will be loose and easily disposable, whereas other debris will be caked on. You might need to use a scouring pad or a sharp putty knife to remove the stuck on debris.
