According to some websites, all we need is some rice, fish, some sauce and oil?

[Although, those websites weren't consistent. If anything, they were all variations of the same thing that ranged from using rice paper as the crust to just using flat out pain rice. Not to mention that there were different variations of what kind of fish to use.

But for the most part, a lot of it is us making it without a real recipe. A lot of it different versions of the same thing as there is no uniform way to cook it.

[Which...could spell trouble.]
