I've never heard of blue. I like rare, but I have real problems cooking steak. Assuming one a proper thickness, by which I mean 20mm give or take, how long should I give it each side in a hot pan?
It's as if I hadn't already given you the answer

...since you ask, different cuts have different optimum cooking methods. So there is no such thing as a preferred method of cooking steak as it depends on what kind of cut.
