The Japanese Burger

By Kaz Okochi of Kaz Sushi Bistro

1/4 pound tofu
1/2 pound ground beef
1/2 pound ground pork
1/4 cup thinly sliced shiitake mushrooms
1/4 cup chopped scallions
2 tablespoons miso paste
1 egg 1 teaspoon salt
1/4 teaspoon pepper
1/4 teaspoon nutmeg
2 tablespoons soy sauce
1/4 cup mirin
1/4 teaspoon finely chopped garlic
1/4 teaspoon grated ginger
1 tablespoon vegetable oil
8 iceberg-lettuce leaves
1/4 cup Japanese mayonnaise
4 teaspoons grated horseradish
4 sesame buns

In a shallow pan, set the tofu between 2 paper towels. Weight it down with a can or bottle for 30 minutes. Let the water drain, chop the tofu, and set aside.

In a bowl, combine the beef, pork, tofu, shiitakes, scallions, miso, egg, salt, pepper, and nutmeg and mix well. Divide the mixture into 4 patties.

In another bowl, combine the soy sauce, mirin, garlic, and ginger. Set aside.

Set a pan over medium-high heat and pour in 1 tablespoon of vegetable oil. Cook each burger for 1 to 2 minutes, until brown on each side, then reduce the heat to low. Cover the pan with foil and cook 4 minutes more. Puncture patty to test if it’s done; its juices should be clear. Remove the burgers from the pan and drain the oil. Return the patties to the pan, raise the heat to medium and add the soy-sauce mixture. Keep the pan moving to prevent the sauce from burning and flip the burgers while the sauce thickens. The burgers are done when they have a thick, shiny coating of sauce. Serve on a toasted bun with lettuce, mayonnaise, and horseradish.
