Oklahoma is really known for its' oil fields and culinary creations like chicken fried steak. Yet there is a new classic that's equally delicious coming from The Sooner State .It's the onion burger and it's gaining in popularity.
J Kenji Lopez-Alt wrote about this yummy treat in yesterday's New York Times Food section.The recipe comes from the Hamburger Inn in El Reno, Oklahoma located in the middle of the state.It was originally called "the Depression Burger" created by Homer Davis and his son Ross at the height of that era. The onion burger as it's now called has become beloved in recent years thanks to W. George Motz , author of Hamburger America and host of First WE Feast "Burger Scholar Sessions" on You Tube. He would shoot these popular patties through a chute through a kitchen window to waiting diners during the pandemic .He's just wrapped up a European tour, introducing the burger to an international crowd. What makes them so delicious. Blame it on a particular odor molecule,3-Mercapto-2-mentelpentan-1-ol or MMP. It produces an aroma like beef broth. Combine it with chopped beef and it makes the burger taste meatier. You do have to slice the onions paper thin, preferably with a mandolin to release this compound as well as thiosulfinates which also enhances the flavor.
what is the recipe? It's taking two medium yellow or white onions and ground beef.It's shaping the hamburger first into round well shaped patties.The onions are then put on top of the burgers, stacked like haystacks. Layer on as many as possible, the higher the better.DO NOT add salt to the onions because it will draw out any moisture. This can ruin the searing the process. Now it's time to cook them, with four burgers in each quadrant of the pan or grill. Use a neutral oil for this however cooking them in butter or a plant based butter will give it a better taste.Smash the burgers with a very sturdy spatula. Focus on the patties' edges to get that crispy finish, The middles should be slightly thicker.It's then scraping the edges off the pan and carefully flipping them onion side down.Use the spatula, tones or even fork to tuck in any stray onion strings. Chef, Lopez-Alt recommends using King's Hawaiian rolls which have a sweet flavor..It's steaming these and then placing the burgers on top of them.. Add cheese and pickles if you want.
The Oklahoma onion burger may be the star of the summer.It's a yummy way to enjoy burgers , enhanced with onion. Try it for a tasty change up from the usual ones.
