There was an episode of Chopped a few years back where they gave the competitors a deckle of beef in the entree round. I think only one of them either knew the other name or recognized the cut. I wonder how many new foods or different names for them they've introduced to viewers over the years? I can think of a number of fruits and vegetables that I hadn't heard of before seeing them on the show, and I've probably seen about half of those in a store since learning of them, and I've tried a few of them, though none of them have made the list of things I buy regularly.
Food shows and the whole foodie community have made some cuts of beef that used to be inexpensive, like flat iron steak, as expensive as Porterhouse!
