ok running back to store tomorrow for some mirin and sake
I bought broth but i have boullion if I really want to make a imitation stock.. I think broth would be fine. simmer it with the ginger, nice handful of the pork, garlic and scallions then strain for the soup base.
Soy sauce tare with soy sauce, sake, mirin , ginger , garlic and scallion.
I might even do the soft boiled egg for them. Marinaded in a soy marinade
