My 14 yo daughter had the opportunity to taste Waygu about a month ago, and immediately declared "this is the best thing I've ever had in my life!" So for her birthday she wants Waygu. By luck, Wegmans had it on sale and I bought a few steaks. They're thin, less than half an inch. I'm thinking direct at the felt line, about 500, a minute each side for medium rare. I'm less concerned about getting a good sear and more concerned about overcooking them because they're so thin. But I could cook a few inches lower. What do people think?
