Steak is indeed beef! Least, generally it refers to beef.
Lemon Cheesecake Definitely look up how to make a tender steak. But let's see... I usually try to err on the side of everything seared on the outside but a little rare. Because overcooked makes beef kinda tough.
Also depends on what cut of beef you're using. Some beef is naturally tough. I dunno much bout stewing unfortunately.
