This monster cut of beef is named after the mythological Norse God of Thunder. The shank is cut from the upper part of the cows leg and then the bone is Frenched. This is a culinary term used when you scrape the meat off the end of the bone so part of the bone is exposed. The cut really does look a bit like a hammer and I'm sure, if necessary could become quite a weapon. This cut weighs just over 4 lbs.
