- 2 tablespoons sake (rice wine)
- 3½ ounces (about 5 tablespoons) Saikyo miso (sweet white miso)
- 1 tablespoon sugar
- 1 large egg yolk
- About 1/3 teaspoon usukuchi shoyu (light-colored soy sauce), preferable, or regular shoyu
- In a small cup, mix the sake with 2 tablespoons water. In a suribachi or other mortar, grind the miso, sugar, and egg yolk to a smooth paste. Add the rice wine and water mixture little by little, grinding all the time. Season to taste with shoyu. Have at hand a bowl half-filled with cold water and ice cubes. Transfer the sauce to the top of a double-boiler, and cook the sauce over simmering water, stirring constantly and thoroughly so you do not scramble the egg, until the sauce becomes thicker, about 6 to 8 minutes. Set the bowl of sauce in the bowl of cold water and ice cubes to cool. Tama-miso may be stored in the refrigerator, covered, for three days. Heat the sauce through before using it.
