Ingredients for Rice with Soy-Glazed Bonito Flakes and Sesame Seeds

  • Leftover katsuo bushi (dried bonito flakes) from making dashi or 240ml katsuo bushi fresh from package

  • 1 tablespoon sake

  • 1/4 teaspoons sugar

  • 1 1/2 tablespoons soy sauce

  • 2 tablespoons sesame seeds, toasted

  • 475ml Japanese short-grain rice

  • 475ml water

How to make Rice with Soy-Glazed Bonito Flakes and Sesame Seeds

If using katsuo bushi flakes from package, moisten with a few drops of sake or water. Finely chop katsuo bushi, then cook in a dry heavy skillet over moderate heat, stirring frequently, until fragrant and mostly dry. Add sake, sugar, and soy sauce and cook over moderate heat, stirring frequently, until mixture is dry and glazed. Stir in sesame seeds and spread on a plate to cool.

Rinse rice in a bowl in several changes of cold water until water is almost clear; drain well in a large sieve. Combine rice and 475ml water in a 3-quart heavy saucepan and let stand 10 minutes. Cover with a tight-fitting lid and bring to a boil over high heat. Cook at a rapid boil (lid will be rattling and foam may drip down outside of pan) 5 minutes, or until water is absorbed. Remove from heat and let stand, covered, 10 minutes.

Serve rice with bonito-flake topping.
