Last year I used a new butcher. Just pulled a venison London Broil out of my freezer. About 1.5" thick. Tasted just like a beef London broil. What part of the animal was it from? What would another butcher call it ?
London broil is cut from a Top Round. With beef you can also bone out a shoulder and cross cut it into a London Broil, however I wouldn't recommend that with venison. The center of Moose or Caribou shoulder can make a decent London broil as well.
