I really try to salt a steak the night before and let it sit in the fridge, gets all that moisture out and creates a perfect crust when it's grilled. I actually did a reverse sear in the air fryer this time, thought it might be sacrilege, living in Texas and all but it was 25* outside and the reverse sear on the grill was going to take WAY too long. The air fryer did a really good job with the thick ribeye (sorry Lanny but ribeye is the only steak worth getting) and then a quick sear on the cast iron and it was DELICIOUS! It was a smaller tomahawk, didn't have the massive bone but still a good sized one. I do find the tomahawks to be a little richer in flavor and the dog devoured the bone, so it was a win all the way around.
As for rub, doing BBQ competitions I really stick to a basic rub of 1/3 cup of salt, 1/3 cup of pepper, 1/6 cup of cayenne and 1/6 cup of garlic powder. Put that on any red meat, chicken, veggies, it's all good with that rub.
