Gave my 9 year old daughter some Medium cooked steak one evening (yeah... I had a little too much beer while cooking)... anyway.. she passed it back to me and said, "it ain't red enough, Dad"
I apologized, "won't happen again darling"
We are a medium rare household (reverse seared of course) leaning toward the rarer side. the only exception is my 7 year old son who claims he doesn't like steak
We are hoping he grows out of that.
