This classic donburi is believed to have been adapted from combining gyu-nabe, a Japanese hotpot that includes beef and vegetables and sukiyaki-don, a rice bowl topped with sukiyaki. "Gyu" means beef and "don" is a shortened word for "donburi" (bowl).
Ingredients (serves 4):
In a bowl, marinate beef with wine or sake, sugar, mirin, salt, soy sauce and grated ginger.
Place onion and dashi in a sauce pan. Cook for 5 minutes at medium heat.
Add marinated beef to the sauce pan, cover with lid and continue to cook for 5 more minutes or until beef is cooked through.
Fill each serving bowl with cooked rice and top with cooked beef and onion.
Serve while hot with optional pickled red ginger.
