Beef is mainly composed of protein (in the form of muscle tissue), fat and water. If you remove the fat, beef is actually about 60% water. Beef muscle fibers are supported by small bands of connective tissue; either collagen or elastin.
The cuts of meat from a muscle that gets a lot of exercise has more connective tissue, resulting in a tougher cut of meat.
When cooking beef stew, if you add 3-5 wine corks, it will tenderize the meat very quickly. The cork is a fiber material from a tree and contains enzymes that have the ability to tenderize meats.
It is best to remove the corks before serving the stew as they are not very appetizing!
