Baron of Beef, A Baron of Beef will generally be anywhere from 100 to 200 pounds, You can't normally toss one into your cart from the meat counter
I think they have the wrong picture on this as it has no sirloin on it, A Steamship Round contains only the Round area of the cow, with no sirloin.
you charge more for Baron of Beef because it contains sirloin than you will for Steamship Round, which does not.
As with all cuts of beef, I'm afraid you have butchers, particularly North American ones, "butchering" the term, and calling a 20 pound or even a 4 pound roast beef a "Baron of Beef". Basically, if it can't feed at least 60 people, it ain't a Baron of Beef. If you can even conceive of cooking it at home, it ain't a Baron of Beef.
I always wanted to tie a beef crown roast every holiday season as a centerpiece in a roast set for the case however there just not enough room to accommodate it.
