Step 1: The first step is to remove the sinewy layer on the surface called silver skin.

Step 2: Slip the tip of a sharp, thin knife under one end of the silver skin.

Step 3: Grab the loosened end with your fingertips. Then slide the knife away from you just underneath the silver skin.

Step 4: Continue cutting away from you, with the knife blade angled slightly upwards.

Step 5: The “cleaned” tenderloins should have hardly any visible silver skin or surface fat.

Step 6: For great flavour, make a paste of oil, garlic, herbs, lemon zest, and spices. Press it into the meat before barbecuing.
