anything above medium is blasphemous, and only kids and faint-hearted women can order medium. The only reason to cook beef through is if it's shit beef (see: taco bell).
Also, to whoever above said Kobe is a cut of beef, it isn't. It's both a type of beef and a label for beef in the US, but they are not remotely similar. the Type of beef is from Wagyu cows raised in Kobe, Japan, and it's the most sublime beef money can buy. The "Kobe" you often see advertised is actually just angus, and not even remotely close in quality to Wagyu beef.
speaking of steak, on saturday I am having a dry aged bone-in frenched ribeye, super stoked, though it set me back a sizable portion of my weekly income.
