has anyone a clue what this is called?
it's filled with red beans, it's sweet and the dough is like yeast dough like in a yeast dumpling ...
Very good observation! The Japanese, well not in every case but, like to prepare food by enhancing the unique cahracteristic of the ingredients, not by adding seasoning on top of seasonig like say French cooking, although there are some similarity between those two.The great thing about Japanese food, is I love every single thing on that list. They really "get" food, the same with authentic Italian food. In contrast, while I like many kinds of American and ethnic food, it's hit and miss.
Like Italian, Japanese focuses a lot on simple quality and skillful preparation. And in Japan, people hold good standards and supermarkets/restaurants have to cater to that. You can get perfect and ripe vegetables in most places, and taste a big difference.
I miss wafuu spaghetti. When I was living in Japan I sometimes made a delicious tarako white sauce spaghetti. I also remember mentaiko pizza toast fondly.I love that Japanese spegetti!
