This recipe creates flavorful Japanese-style burgers using a blend of ground sirloin and pork, incorporating panko and Japanese seasonings. They are served with a unique wasabi-infused ketchup, offering a delightful fusion of flavors.
Combine the panko and milk first and let it soak thoroughly before adding to the meat mixture; this helps keep the burgers moist. Be careful not to overwork the meat mixture, as this can result in tough burgers. Mix just until the ingredients are combined. Use sesame oil on your hands when forming patties to prevent sticking and add a subtle aromatic note. Cook patties to an internal temperature of 160°F (71°C) for food safety. Allow cooked burgers to rest for a few minutes before serving to retain juices.
