Delicious Japanese comfort food.Calm your insides or warm yourself in the morning with Taimatsu's pickled plum rice porridge. Known in Japanese as Kayu, this porridge is made using fluffy, chewy Koshihikari rice from Niigata prefecture, and flavoured with umeboshi pickled plum from Wakayama prefecture. Enjoy this soothing, yet refreshingly tart, plum flavoured porridge as it is, or add a sprinkle of bonito flakes for extra umami.
