First and foremost go out and get some grass fed beef preferably a ribeye, filet or chateaubriand. Get a big bowl and mix together brown sugar(the base), ground espresso beans, kosher salt, powdered chipotle pepper, ground black pepper, white pepper, minced dried onion, ground ginger, and cayenne pepper. Use that as a dry rub. Make sure you pat the steaks dry before applying the rub. Let them sit at room temp for about 30min with the rub then BBQ medium rare. Let the steak rest for 10min off the grill and voila, best steak you'll ever have. If you've got a smoker I do it for 20min @ 200 degrees and they come out perfect.
Once you have grass fed beef you'll never go back. It's 100x healthier then corn/grain fed beef, more tender, leaner, packed with omega 3 and all around goodness. The only problem is cooking it because the fat content is so low that they dry up much quicker so the preferred doneness is rare to medium. I screwed up my first few but realized how much more they cook after pulling them off and letting them rest. The rub also helps lock in the moisture without them being too rare.
Grass Fed Ribeye's, the dark one was with the espresso bean rub, the other just a small amount of kosher salt and black pepper
Here's a couple of filets with the espresso bean rub. I've never been a huge fan of filet and I thought these were incredible.
