Sorry i am way late on this one. I asked my uncle in Japan (he's American, just a 65 weeb currently backpacking through Japan with my aunt for their retirement) for advice on something to make. He was currently in Hiroshima and told me to try making this local street food. Unfortunately i didn't realize how hard it would be to get some of these ingredients in rural Ohio, but i finally got everything for this recipe. luckily there is an amazing little Asian grocery store in Findlay that hooked me up with everything i needed and i am incredibly happy with how they turned out!
