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 :-).
To achieve a crust on the outside while keeping the interior of the steak cooked to your liking, you need to have two different temperatures set on your grill. In order to get those nice grill marks, you need to heat your grill to high heat to essentially sear the steaks. To determine the heat is hot enough, you should be able to hold your hand about an inch over the grill grate for 1 second before it feels too hot and you must pull it away.
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.
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.
