Makes two servings.
- 1/2 lb thinly sliced beef
- 2 T butter
Fry the beef in butter in a large frying pan.
- 1 onion
- 2 tsp brown sugar
- 2 T concentrated soup base (dashi or hontsuyo)
- 2 T soy sauce
- 2 T mirin
Slice the onion thin. When the beef is mostly cooked, add the onion, brown sugar, and sauces. Cover and simmer. Uncover and reduce the sauce before serving if desired.
- cooked white rice
- furikake (optional)
Serve over white rice. Furikake makes a nice garnish.
The best beef I've used for this is a very thinly sliced beef, rolled into tubes and frozen. It's from an Asian grocery store, and probably meant to be used in hotpot. If you can find something similar, it'll give you a better result than trying to slice the beef super thin yourself.
If you use fatty beef, consider skipping the butter; or perhaps cooking the beef without butter, draining the fat off, and adding the butter later.
