You can cook up some breathtakingly beautiful cherry blossom rice using this method. It makes me happy just looking at it. It also has a comforting, gentle flavor.
The farmer granny from whom I purchase my direct-from-the-producer vegetables shared this recipe with me. She says it's the more luxurious version of standard daikon radish rice.
You could also reduce the amount of salt and put in a pickled plum instead. You can also make this with 2 rice cooker cups' (360 ml) worth of rice as well, and it'll still turn out fine.
Enjoy Japanese food around the world.
