Japanese Burgers With Wasabi Ketchup

• 1/2 cup ketchup
• 2 tablespoons soy sauce
• 1 tablespoon wasabi paste
• 1/2 cup panko or other dry bread crumbs
• 1/4 cup whole milk
• 8 ounces ground sirloin
• 8 ounces ground pork
• 1/4 cup finely chopped white onion
• 1 1/2 teaspoons soy sauce
• 1/2 teaspoon salt
• 1/4 teaspoon pepper
• Sesame oil, for coating hands
• 4 brioche buns, for serving

1. Prepare the wasabi ketchup: Whisk together the ketchup, soy sauce and wasabi paste.
2. Make the burgers: Prepare a grill for medium heat.
3. In a large mixing bowl, combine the bread crumbs and milk and let rest 2 to 3 minutes.
4. Add the sirloin, pork, onion, soy sauce, salt and pepper.
5. Knead the meat until it becomes sticky and binds together; divide into 4 parts.
6. Lightly dab your hands with sesame oil.
7. 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.
8. Make a shallow indentation across the center of the patty with the side of your hand, to keep it from puffing while it grills.
