Wow, after a decade and a half, I think I finally found this again. I hope this is what I was looking for. I remember watching an episode of an anime when I visited family in China, and there was a kid that made noodles with meat or something inside them, and something about angular shapes. 15 years later, I still remember that. I only watched the one episode because as a 6 year old, you don't really have shows you would want to watch in a foreign country, but I've been casually searching for it ever since. I really hope this is the series, because I am dying to try cooking that. If not, it's still pretty fun so far
Edit: Yup, seems like this was it! Well. Kind of. I remember them going into more detail about some of this, but it might be an anime only thing
