Well, I am a Chef, so dont listen to me..... Its hard to beat tenderloin, however taste is a lost art, do you know what a steak, tastes like? most people dont, they used to, but today everything is doused with bizarre spices, rubs, and marinates, all have a place of course, but if its beef you like to taste, my recomendation would be to go to a non commercial butcher, 95% of comercial beef is not grass fed anymore, ergo, the lack of taste. Grass fed beef, try it once, if you are over 30 Years old you will go" where did I taste that last? Middle school,! before Governement started to subidize corn, Today's Cattles are kept in pens, eating corn, then get slaugtered because they would expire in a few month anyway. Sorry to rain on your parade, but its what I do for a living.
What is the best piece of grilled beef? its a grass fed piece of Flat iron steak, a disrespected piece of meat really.
Salt, pepper, on the grill medium hot, till pink, then eat as a piece or cut up in strips, squeeze some lemon on it, and use as topping for a nice fresh mixed salad. The best piece of meat you will ever taste.
More info:
Definition: Probably one of the must under appreciated steaks, the Top Blade Steak may be more commonly called the "Flat Iron Steak". This tender and flavorful little steak is cut from the top blade roast and comes from the chuck primal.
Perfect for the grill (or broiling) this steak has such a great flavor that it requires no real seasoning. Tender enough to cook through medium without a marinade (though I would if I were force to cook this beyond medium). This is a perfect steak on it's own.
Also Known As: Flatiron Steak, Top Boneless Chuck Steak, Petite Steak, Lifter Steak, Triangle Steak, Book Steak, Chuck Clod Top Blade, Butler Steak, Shoulder Top Blade Steak
