Removing Fat, Membrane and Gristle
- Place the meat on a board with the rounded, neater side of the fillet uppermost.
- Start cutting and pulling away the fat from the wide end.
- Cut away all the gristle and fat that lie along one side of the fillet.
- Cut off the large lump of fat that is attached to the wide end.
- Turn the fillet over and pull and cut away the strip of fat and gristle.
- Return the fillet to its original position. Using a sharp knife, remove the shiny layer of membrane. Your beef should now be completely free of fat, membrane and gristle.
Preparing the Fillet for Roasting
- Neatly secure any loose ends of the fillet with kitchen string. For more even cooking, fold the thin end of the fillet under itself and tie it.
- If you do not want to roast the fillet whole, you can divide it into smaller pieces:
- The thin end - small filet mignon steaks
- The centre - medium-size tournedos
- The wide end - a small joint or Châteaubriand
Châteaubriand is made by wrapping the meat from the wide end in a clean cloth, and flattening it to half its original thickness.
