I’ve never heard of this Pork content thing or the other stuff in the above article.
In My world Hamburger Steak is a well packed Large Beef Burger Hand formed type patty that is minimum thickness of 1/2” ip to 1+” or more in thickness and as big as 6” x 4” cooked to order seasoned with Kosher Salt and Freshly ground Pepper and served with Brown Beef flavor Gravy, choice of Potato and a Vegetable of choice with a Bread usually Texas Toast for cleaning up the Gravy.
Option for the Gravy is no Gravy but he Steak Sauce of choice like A1 or other brand. Yes You can still get the Texas Toast:
Salisbury Steak is a Beef Steak that’s a good quality thinly sliced steak (1/4” - 1/2” thick) and run through a Tenderizer, seasoned with Kosher Salt and Freshly Ground Black Pepper and Minced Fresh Garlic or Garlic Powder (what many people would call a Cutlet.) Cooked to Order and served with Brown Beef flavor Gravy, Baked Tater and a Veggie of choice and a Dinner Roll.
Then We would be moving in to a Real CFS (Chicken Fried Steak) if Anyone would like the details on that I will be happy to share the info.
“Salisbury Steak is a Beef Steak that’s a good quality thinly sliced steak (1/4” - 1/2” thick) and run through a Tenderizer”
What you describe is actually
called a cubed steak, usually
tenderized round steak, which
is drenched in milk/egg/flour
and deep fried to create a
chicken fried steak.
