Preparing Basic Ingredients Beef

Rinse beef, remove tendons, and cut into desired size.

Before cooking, pound the beef with a meat tenderizer or the back side of a knife to keep the beef from curling up during cooking, and to make it more tender.

When cooking pressed meat, tie it up with kitchen string to make a nice shape, and boil.
