Beef tacos are made from the following parts:

Fatty beef tacos are usually made from the back muscles of the cow's loin and the abdominal boneless muscles, which are made into thin slices with special machinery, or the meat on the cow's leg.

That is to say, all the meat on the cow except brisket can be made. It is the meat that is cut from the cow with advanced technology. The term "fat cow roll" originated in the United States at first, which refers to the beef that is placed inside a hot pot, and later fat cow rolls are mainly used in hot pot restaurants.

Introduction to Beef Rolls

Beef rolls are also known as fat, which is translated as beef in hot pot, which is beef cooked in a hot pot, and it is not the name of a class of cattle.

Nor does it refer to an obese cow, but rather the meat from a cow's loin, abdomen or back is processed and sliced into thin slices so that it has both lean and fat meat, which is easier to cook and takes less time to cook than usual, and is generally used for shabu-shabu and other purposes.
