I can't think of a better place for hard to find info. Years ago there was a Korean Bakery that made the best rolls I think I have ever tasted. They were football shaped with an indention on top that was filled with about a tablespoon of butter, scallions and salt that had been simmered until tender and simply placed in a puddle on top. I have searched the net for years and haven't found anything that even sounds close. Any help would be appreciated. There might be a time when I don't have to ask so many questions, but I don't see that happening anytime soon.
