Premium? Somewhat depends on which bits of the horse. For those that still eat shop burgers, I won't speculate on just how much some bits might be lacking in anything resembling 'premium', but I can think of a few bits less than premium.
Same applies to the beef people might expect to get. Which bits of 'beef'?
For anyone tempted to offer suggestions, please don't. Let those that like their burgers continue in blissful ignorance of what can happen.
