For the Sauce:
- 10 ounces Silken Tofu
- 1 cup Panko Breadcrumbs
- 1/2 Onion
- 10 ounces Ground Pork, or a mix of ground pork and veal
- 1 Egg
- 1/4 teaspoon Salt
- 1/4 teaspoon Black Pepper
- 1/4 teaspoon Ground Nutmeg
- 4 tablespoons Ketchup
- 2 tablespoons Worcestershire Sauce
- 3 tablespoons Sake
- 2 tablespoons Mirin
- 2 tablespoons Butter
Place the tofu in a bowl and whisk it to break it apart and make it into a paste.
Add the panko to the bowl and mix with the tofu.
Finely chop the onion and add it to the tofu and panko mixture.
Add the mince, an egg and all spices to the mixture and mix it well.
Roll the mixture into 8 even-sized patties and fry them in a frying pan on medium to high heat.
While the patties are frying, mix together all the sauce ingredients in a bowl and set aside.
Once the patties are fully cooked remove them from the pan and set them aside on a plate then cook the sauce in the pan.
Bring the sauce to boil then turn the heat off.
Serve the hamburgs with whatever vegetables or sides you like, then drizzle the sauce on top.
