to remove the silver skin from a cut of meat slip the tip of a sharp knife just underneath one end and slice with the knife angled upward to the end to create a handle next holding the handle taut and your knife facing the other direction with the blade angled upward slice off the entire strip of silver skin
repeat procedure until all silver skin is removed
With a few quick swipes of a sharp knife, your pork or beef will be ready to cook.
