Are these ribeye cap steaks?
The meat on each side of the eye of fat is different. On the one side the meat is more tender, fatty and more juicy. It's like eating two different cuts of meat.
I've always bought ribeye from the supermarket but got these steaks from the butchers and noticed how different they look.
