Trimming silverskin and fat

Beginner Butchery and seafood

Trimming silverskin and fat is removing the thin, shiny sheet of connective tissue and excess hard fat from cuts like tenderloin, ribs and roasts.

How do you do it?

1. 

   1Use a thin, flexible boning knife. Slide the tip under one end of the silverskin to make a tab about 1 inch wide.

2. 2Grip the tab with your free hand, held flat and behind the blade.

3. 3Angle the blade slightly up toward the silverskin and slide it along while gently pulling the tab back, so you shave the membrane, not the meat.

4. 

   4Trim fat thicker than about 1/4 inch on quick-cooking cuts; leave a thin layer for flavor.

Why does it work?

Silverskin is mostly elastin, a stretchy protein that, unlike collagen, does not melt into gelatin no matter how long you cook it. As it heats it shrinks, so it curls the meat out of shape and stays chewy. Thick hard fat on a fast-cooked cut doesn't have time to render, so it stays rubbery.

What are the common mistakes?

• Angling the blade into the meat — you carve off good meat with the membrane.
• Trimming all fat — leaner, drier, less flavorful results.
• Using a dull knife — it slides off the membrane and skips toward your hand.
