Set the sous vide bath to 128 F/53 C. Stage the trimmed hanger steak into a dedicated vacuum bag. Seal and sous vide process for 10 hours. This will tenderize and pasteurize/preserve the protein. Submerge the unopened package in iced water until 70 F/21 C is achieved--this usually takes about 15 minutes. Refrigerate the beef to 40 F/4 C after cold shocking. Increase the heat in the bath to 135 F/57 C. Carefully lower the in-shell egg into the bath and process for 75 minutes to pasteurize. Shock the in-shell egg in cold water to 70 F/21 C and refrigerate at 40 F/4 C.
Cut the steak into small cubes, approximately 1"/3 cm. Finish chopping the meat using a food processor on "pulse." Traditional recipes call for chopping the meat by hand, frequently delegated to apprentices or as punishment for impertinent cooks. A meat grinder can also be used utilizing a coarse plate. Avoid chopping the meat too finely. Stage into a shallow bowl. 
Add the green onions. 
Add the capers. 
Add the mustard and ground black pepper. 
Add the Worcestershire sauce. 
Sprinkle with a pinch of salt or your favorite seasoning blend. Mix well. 
Form into a ring. Set aside. 
Lightly butter and toast (or grill) the baguette. 
Remove the ring from the steak tartare. 
Sprinkle the plate with green onions and capers. 
Chopped parsley. 
Drizzle with a few drops of extra virgin olive oil. Cut the toast into desired shapes and stack behind the cylinder. Crack the pasteurized egg into a bowl and use a slotted spoon to drain off the egg white. Position the yolk in the middle of the steak tartare. Once mixed in, the yolk provides a rich, moist texture to the dish. As a matter of preference, many chefs omit the egg yolk out of consideration for squeamish guests. 
Sprinkle with volcanic black salt (optional) and more parsley if desired. The egg yolk is then ceremoniously mixed into the meat "at table."
