Remove any excess fat or sinew and finely dice the @beef loin{120%g} or beef fillet.

Peel and finely dice the @red onion{15%g}.

Mix together the diced beef and onion in a #mixing bowl{}, season with @salt{1/4%tsp}, @pepper{1/5%tsp} and @Worcester sauce{15%g}. You can also add some finely chopped parsley to the tar-tar.
