Drool....Ribeye is one of my favorite cuts. I've always grilled it straight HnF, have to give this reverse sear method a try.
That finished plate looks like a great match for a nice glass of Cabernet....or Guinness!
I used to grill other cuts of steak frequently (once or twice a week.) Now I do them way le$$ often but when I do they are big, thick, fatty bone-in rib-eyes. Although I wouldn't turn down a T-bone.
