Take a saucepan and add all the broth ingredients (300 ml dashi stock, 2 tbsp Japanese dark soy sauce (koikuchi shoyu), 2 tbsp mirin, 2 tbsp sake, 1 ½ tbsp light brown sugar, 1 tsp Japanese light soy sauce (usukuchi shoyu), 1 tsp grated ginger root, ¼ tsp grated garlic and ½ tsp Chinese-style chicken bouillon powder). Mix well and place on the stove over a medium heat.
Add the onion to the broth and bring to the boil. Once bubbling, lower the heat slightly and simmer until the onions are softened to your preference.
Add 150 g thinly sliced beef to the broth and continue to simmer until cooked through.
Divide 2 portions cooked Japanese short-grain rice in serving bowls and top with the beef and onions. Drizzle 1-2 tbsp of the broth over each bowl.
Top with red pickled ginger (benishoga) and Japanese chili powder (shichimi togarashi). (See in post for additional topping ideas.)
Enjoy!
Notes
Use thinly sliced beef (1-3mm thick) like short plate, flank steak, or "for Hot Pot" packages for authentic texture and flavor.
