Method
- Whisk the soy, mirin, sugar, and ginger together, then marinate the beef slices for 15 minutes.
- Sear the beef in batches in a screaming hot pan for 30 seconds per side until charred.
- Reduce the leftover marinade in the pan to a glaze and toss with the seared beef.
- Pile the beef over hot rice, top with an onsen egg, pickled ginger, and a drizzle of glaze.
Cooks notes. Recipes are tested in a US home kitchen. Substitute lemon for lime if you must, but the result will read brighter. Salt to taste -- our quantities skew toward kosher.
