Good grief, I could approach this in a number of ways.
When I grew up in Brooklyn I knew almost nothing about beef.
But then as a teen I went to work in a supermarket part time. Forty years ago rules were different, and if you worked hard you could find yourself doing all sorts of chores in the place.
Even doing some simple cutting of meat (someone had to cut the meat when the butcher disappeared for an hour or two to be with his latest lady friend).
And I was always friendly with the customers. Not having any idea what you are doing is not always an impediment to serving the customer - sad to say.
But it was another number of years after that before I learned what cut of meat was tasty and how it should be cut and cooked.
My education with cooking, and particularly meat cutting, has been in fits and starts. I envy and appreciate those who have had a formal education in the field.
To the poster, you cannot just go to the store and buy a 'steak' and go home, cook it in any way you feel appropriate, and expect success.
But cooking is not rocket science or brain surgery and if I can learn something about it so can you.
