Ingredients
Directions
Prepare
Cover the eggs in boiling water and let them sit for 20 minutes so they are soft inside and not hard. Carefully peel off the shell.
Boil the beef and drain the water.
Cook the beef and sauce
Combine sake, mirin, soy sauce, and sugar in a frying pan. Stir over medium heat.
Add the beef and cook. Before all the sauce evaporates, remove the beef.
Add water, dashi, grated ginger, and onions to the sauce. Cover and boil. Mix in the beef.
Serve
Put the steamed rice in a bowl and top with the sauced meat.
Arrange the soft egg and pickled ginger on top. Top with scallions and shichimi seasoning.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Soft-set yolk and white add richness and a creamy coating over the rice.
- Beef
- Provides the savory, tender meat that absorbs the sweet-salty sauce.
- Soy sauce
- Supplies salt and savory depth that defines the sauce's flavor.
- Sugar
- Balances the saltiness of the soy sauce and helps the sauce caramelize slightly.
- Onion
- Softens while simmering, adding sweetness and body to the sauce.
- Mirin
- Adds sweetness and gloss to the sauce.
The step that matters
Remove the beef before the sauce evaporates. Once the sauce reduces too far, the sugars can scorch and the beef becomes dry and tough. Removing the meat at the right moment keeps it tender, and it rejoins the sauce later.
