This simple takikomi gohan (mixed rice) has only sweet potatoes and shimeji mushrooms. It's seasoned well, so it's delicious even when cold.
I wanted to eat sweet potato rice, so I cooked with mushrooms.
At our home, we add just a tad more water than the level for 2 rice cooker cups (about 2 to 3 mm higher). The mushrooms don't have to be shimeji mushrooms. Add your favorite.
