Ingredients

1 pound ground beef (80/20 ratio)

1/4 cup onion, minced

1/2 teaspoon kosher salt

1/4 teaspoon granulated garlic

1/8 teaspoon celery salt

pinch cayenne

1 teaspoon Kikkoman soy sauce

1 egg

1/2 cup Japanese panko bread crumbs

3 Tablespoons mayonnaise

Preparation

Gently but thoroughly combine the ingredients. Form 4 patties making a slight indentation in each. Pan fry or broil in a cast iron skillet over medium heat. Cook through, about 8- 10 minutes. Hamburger steaks should be juicy, but well done, like meatloaf. Serve with gravy of your choice.
