Japanese Burgers With Wasabi Ketchup

Step 1

Prepare the wasabi ketchup: Whisk together the ketchup, soy sauce and wasabi paste.

Step 2

Make the burgers: Prepare a grill for medium heat. In a large mixing bowl, combine the bread crumbs and milk and let rest 2 to 3 minutes. Add the sirloin, pork, onion, soy sauce, salt and pepper. Knead the meat until it becomes sticky and binds together; divide into 4 parts.

Step 3

Lightly dab your hands with sesame oil. Using your palms, roll each part of the meat into a ball, then pat the ball flat, shifting it from hand to hand, to form a 1/2-inch-thick patty. Make a shallow indentation across the center of the patty with the side of your hand, to keep it from puffing while it grills.

Step 4

Grill the burgers, flipping twice, until browned and cooked through, with no pink in the middle, about 10 minutes. (Alternatively, they may be broiled or sautéed.) Let rest for 2 minutes. Serve on buns, topped with some wasabi ketchup.
