Prime strip on the Blackstone
The Blackstone sub is full of people that don't know how to cook steaks, so in case any of them wander into here, this is my method:
Dry brine for 24h, uncovered in the fridge. Take the steaks out a couple hours before cooking, and fresh grind coarse pepper just before grilling.
Half of the griddle on high, half on low.
Set an aluminum pie plate on the low side with a stick of butter, a little vegetable oil, some smashed garlic cloves, a few glugs of worchestershire, and a few sprigs of rosemary and thyme.
Sear on the hot side for 3 minutes. Flip to a different part of the griddle and baste with butter. Sear another 3 minutes, flip, baste. Now, flip every minute, basting after each flip.
When the crust gets where you like it, turn off the hot side and move to the cooler side. Continue to flip and baste every minute.
When you're at the internal temp you want, remove to rest on a rack for at least 10 minutes. Plate and drizzle with butter.
