While there are many dishes that highlight the natural sweetness of Japanese sweet potatoes, Satsumaimo Gohan is an excellent choice if you are looking for a rice dish to enjoy. The lightly seasoned rice perfectly complements the flavor of the sweet potatoes.
Place a sieve over a bowl, add rice, and rinse it with water. Repeat this process several times, changing the water each time.
Soak the rinsed rice in water (as specified in the ingredient list) in a pot for at least 30 minutes.
Cut the sweet potatoes into small cubes and soak them in water (not listed in the ingredients) for about 5 minutes to remove any astringency.
Mix sake and salt in the pot. Evenly distribute the diced sweet potatoes over the rice.
Cover the pot and bring it to a boil. Once boiling, reduce the heat to low and cook for 11 minutes (10 minutes for 2 servings, 12 minutes for 6 servings).
Turn off the heat and let it steam for 10 minutes with the lid still on.
