There was a stand near Yoyogi Park selling what they called baby castella (castella being a type of cake popular in Japan). You can see the lady piping in some fresh batter into the moulds.
I’m sure there are people out there who can say no to hot, fresh little balls of cake. I’m not one of those people. I ordered a dozen.
(And no, there aren’t a dozen of them in that photo. I was so excited to eat these that I just immediately laid into them; it was only after eating a few that I remembered I should probably take a picture.)
These were really simple, but really good. They were kind of like sweet little pancake balls. They were hot and fresh, with a very lightly crispy exterior and a fluffy, chewy interior.
