The one-hour cooking time is relative. How long you should cook the beef depends on the cut and the thickness of the slices. A more tender cut will require a much shorter cooking time. The downside is that the meat won’t have sufficient time to soak up the seasonings. The meat will probably be tender long before the sauce has thickened to a paste. And that is why I chose brisket. The fat added so much flavor too.
Spread the beef slices on the hot oil. Leave for a minute before stirring. Cook the meat until the edges start to brown.
Pour in the soy sauce, sake and mirin. Stir in the sugar.
Add the ginger slices then pour in a cup of water.
Bring the liquid to the boil. Turn the the heat to low. Cover the wok or frying pan and cook the beef until tender and the cooking liquid has turned into a thick paste.
Serve the beef shigureni over rice. Sprinkle with toasted sesame seeds.
