Beef – Should truly fresh steak (i. e. still purple) have a smell

When you are dealing with very high end ingredients, it is more important than ever to let the product speak for itself.

At the restaurant, we rarely use Wagyu, but when we do it is fantastically simple: salt, fresh cracked black pepper. Sear and mark it on the grill, and finish in the oven. A little melted butter on it when it comes out, and that's all.

Do be aware that when you are cooking Wagyu (or, if you're very lucky, Kobe), you actually want to take it to at least medium rare, or even a little bit beyond. I know, that's heresy, and it's coming from a person who likes his steak cooked only to the point where a competent veterinarian could actually resuscitate it at the table. The reason is that when meat is as highly marbled as Wagyu (that is to say, when it has such a high distribution of intramuscular fats), you actually need to cook it further than a lean cut in order to melt the fat and extract all the flavour.

Beyond that, I would agree with Treblekicker. Practice on less-expensive steaks first. Learn how to really maximize the essential beefy flavour of a not-great steak; those lessons will make sure that as you move upwards in quality, you will be getting the most bang for your buck.

So for cooking steaks, a few guidelines:

• Medium is overdone. Seriously. Learn to love your steak red, there is a LOT more flavour
• Learn how to check for doneness by touch; cutting into the meat will release juices = losing flavour. To do this, hold up your left hand, palm facing you. Feel the pad at the base of your thumb. That is blue rare. Touch your forefinger to the tip of your thumb. That is rare. Do this sequentially with the rest of your fingers; that will be med-rare, medium, and well done in order. Well, that's North American colours; the French go slightly less for each level of doneness.
• There is conflicting advice on seasoning (salt and pepper) your steak. Thomas Keller maintains that meat should be seasoned 20 minutes before cooking and left to rest. Harold McGee (I think it was him) says that steaks should only be seasoned after they are flipped. I prefer seasoning before grilling, as the salt helps draw out some moisture which therefore assists in the Maillard reaction (browning and accompanying flavour development).
• Always let your steaks rest a few minutes after cooking. This redistributes juices throughout the meat. In practice, this means taking steaks off the grill or out of the pan a bit before they are done, as carryover cooking (residual heat) will continue to cook the meat.
• Only flip steak once. Try to keep an even cooking time on each side so that the inside cooks evenly. There is a caveat to this however! If you are cooking in a pan, frequent flipping (every 30 seconds or so) will create a much more evenly done steak, and bastes the meat in its own juices. This will come at the expense of slightly less browning, but will be significantly more tender. This is also the best technique for cooking hamburgers in a pan or on a flat-top grill.
• Never squish your steak with your tongs. This presses juices out of the meat.

That's all I can think of for now.

A good Sirloin (New York Strip steak) has a reasonable marble of fat, so you should not have to worry about edge fat

If you like your fat, pull/trim the silverskin and fat off and render the fat in a medium hot pan BEFORE putting the steak in. When enough fat has melted for your taste, cook the steak in the fat at the temperature and time you like

Add fresh herbs or garlic to the rendering fat for extra zing!
