Chef Tom from all things barbeque located in Wichita, Kansas makes great cooking and instructional videos.  In this quick 5-minute video he shows us how to make beef tallow using fat trimmings from beef.

Chef Tom is using the beef fat trimmings from a brisket, but tallow can be made from beef fat trimmings from all areas of the animal. In addition, it is not necessary to use a grinder as fat trimmings can be cut by hand into small pieces using a knife.
