I ain't jewish and a ribeye has more fat and marbling than a porterhouse and it's not demand you can buy which ever cut you prefer.
If you think a whole class of people eating one type of steak has no bearing on demand, I can't explain it to you. Eat what you prefer, but what I said will drive the price up some, whether you believe it or not. I like a ribeye but prefer a porterhouse. Each to his own. I eat a lot of sirloin because it is a bargain compared to the other steaks. I also eat a lot of deer steak, and not all of it is backstrap or tenderloin but the cuts off of the ham, with each muscle separated out. miles
