I think the Bottom Round ( semitendinosus muscle ) is one of the most versible muscles to merchandise from. The Top Round is the largest muscle in the round, and gristle-free when trimmed correctly. The Bottom Round has all the great flavor of the Top Round, but not as big and has a slightly tighter grain. It makes a great roast beef, and some of the best cube steak you’ll ever taste.
Hi agree that the bottom round flat makes good roast beef provided you know how to cook it. You've got to cook it slow on low temperatures. I also agree that it makes great cube steaks. However, bottom round steaks cut for frying or broiling is just about as tough as a "Greek wrestlers jock strap". LOL>
Incidentally the price of cube-steak at Walmart here in North Augusta, S.C. is (are you ready for this) $6.39 per lb. And the package says USDA Inspected. I checked the establishment number and Tyson now is cutting for them. They were with National many years but now that the Brazilians own them they quit having them cut the tray ready meat. .
