White Castle getting nostalgic with 1921 burger

White Castle is returning to its roots with a century-old version of its signature product as its 100th year draws to a close.

The burger chain’s founding location in Wichita, Kansas, which opened on March 10, 1921, is recognized as the first fast food restaurant. The company moved its headquarters to Columbus in 1934.

“As a family-owned business, to be able to celebrate our 100th birthday has been really gratifying,” Vice President Jamie Richardson said. “We’re excited about what comes next.”

The chain recently released the 1921 slider, mimicking the first fast food burger cooked 100 years ago.

“For us it’s something that seems perfectly appropriate,” Richardson said. “It hearkens back to when we started.”

Modern sliders use square patties prepared on a bed of onions. Five holes are poked in the beef to help the meat cook faster and let the onion flavor absorb.

The original sliders, however, were a ball of meat crushed into a circle and cooked on a grill. The 1921 slider will be seared, and seasoned, and topped with caramelized onions, cheddar cheese, a slice of roma tomato, lettuce and pickles, a news release said.

White Castle founder Billy Ingram came up with the idea of crushing beef meatballs on the grill, and even developed an industrial spatula suited to the task.

The national restaurant chain altered its burger-making technique in 1954, Richardson said.

“One of our team members, Earl Howell, put a message in a suggestion box that said if we put five holes in the meat patty, they would cook a lot faster,” he said. “Earl Howell was on point.”

Anyone with the White Castle app on their smartphone and signs up for the Craver Nation loyalty program is entitled to a free 1921 slider, the release said.
