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 (not listed in the ingredients). Repeat this process several times, changing the water each time.
Soak the rinsed rice in water (as specified in the recipe) 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.
Notes
You can store it in the refrigerator for up to 2 days.
