1) The best steaks for Storage are Hands down Steaks with-out bones in them, T-Bone, Porter house..... The steaks that will Freeze and stay in a cooler the longest are non-Boned NY-ers,Filets, Ribeye, Etc.. The steaks with the Most flavor tend to have more Fatty Areas in it, such as "Marbleing", this is the little white fat specs in the Steak itself, The good stuff. One of the most flavorful peices of meat is the Ribeye, a very fatty steak but its worth the carving with your fork and Knife to eat just the Meat. A nice all around Steak on the grill or in the pan is a New yorker. they tend to be squaresh in shape and desent in size and they are easy to spot marbleing in , easy to cook and Best medium rare, "Squishy not firm when pushed on while cooking." Filet is the Softest and a very well eating steak, if cooked properly it can almost be cut with a fork, can be eaten very rare, and pretty leanient to cook. "Want squishy for Medium rare, Firmer for more well done".
2) The meat when it is bought is usually only a few hours to a few days Old after cut therefore the meat has not seen much oxygen so it is VERY red. When you go to cook the steak it might be turning a little Brown, this is just Air getting to the beef, its FINE. You can tell if meat is bad by the smell, TRUST me you will smell if its bad, It will be a nasty Sour smell that cant be mistaken, smells like old gym socks (If you could imagine that). Granted when smelling any Fresh meat it isnt going to smll like Roses.
3) You can make a nice Marinaded steak with the pre-mades like A1-Steak marinade, and Etc.... To make a nice tender Marinaded steak place the Marinade into a container large enough to hold the liquid and a few steaks if cooking for others. Place the liquid into your container and the steaks right into it like your bathing them, you cant stab them a few times with a knife or fork to insure Penetration of flavors. Cover the container with Plastic wrap and let sit for an Hour up to a Day, The longer the more Marinade flavor will be tasted in the meat after cooked. When ready to cook the beef, take it right out of the Marinade bath and place onto a grill, or a pan with light oil in it. Flip every few minutes unil (squishy for Medium rare, Firmer for more well done). And enjoy, Steak is best with Potatoes, Asperagus, and Rice.
