Rather than adding any seasoning, including salt and pepper, to their classic Steakburgers, Steak 'N Shake solely relies on the Maillard reaction for flavor. This is the browning that occurs when amino acids and sugars combine with high heat. I was able to peek into the grilling station at the restaurant to see cooks squashing ground beef "pucks" flat onto the hot grill to trigger the fast browning process. This was good information, but no amount of spying into the kitchen provided me with any information about which cuts of beef are used to make those burgers.

The term "Steakburger" doesn't tell us much, since practically any cut of beef can be a steak until it's ground up, and there are conflicting reports about which cuts up beef are used. One article I found states that the burgers are made with chuck, rib-eye, and brisket, while another claims it's a combination of ground round, sirloin, and T-bone steaks. A waiter at the restaurant told me it's all from porterhouse steak, which is both strip and tenderloin. 

Completely confused by my research, I decided to bust out the meat grinder and taste test all three combinations, plus several others. My tests paid off. Follow my Steak 'N Shake Double 'N Cheese Steakburger recipe, and you'll have a perfect match to the eighty-year old Midwest original.
