Skirt steak breh.but you can use the Steak Umm brand for a faster cook without going through the shaving process. The meat cooks in less than a minute.
I went ahead and baught a Carbon Steel Griddle insert that can convert my grill to a griddle just waiting for it to come in. At that point I don't see a reason to get a Blackstone. Any brothers out there notice a different in just using a griddle insert??
That's all you need.
It's just a griddle. Heat on a flat surface.
Only difference is, once you are done using the griddle, you actually have a regular grill and can grill other stuff. Someone with a dedicated Blackstone might not have that option.
People have been doing the "griddle" for 60 years probably longer using a sheet pan for various things, veggies for fajitas etc. and of course people have dropped pancake batter and eggs on it.
Some people use a dedicated device. Others use a device and use the attachments. I have the rotisserie for my smoker and grill, cast iron grill grates, griddles, and such. But I use my grills year round.
