Try to get a cut of meat at least ½ thick since thinner is more likely to dry out fast, thus a tough cut when plated.
Grilling
Use this per pound of meat, I use a marinade of:
1 Teaspoon of Korean soy sauce, it is lower in sodium than American soy sauce.
1 Teaspoon of Jack Daniels
Place your steaks and the marinade in a zip lock bag, overnight in the fridge.
The day you cook the steaks take them out and coat them with olive oil, back to the fridge.
When you are ready for cooking, take out the steaks and place them in a pan and season them to your taste.
Cooking:
Have the grill preheated to high for gas at least 10 minutes prior to cooking, charcoal should be hot enough where you cannot keep your and more than 2 seconds above the hot coals.
Sear the meat 3 minutes on each side, use a spatula type or tong turner, never a meat fork!
If you do it properly your steak should produce a light sauce of its own on the plate, and for goodness sake never use a paper plate.
