In hindsight it doesn’t make sense that a pacific nation would make sushi from Atlantic salmon…

That's like saying pizza isn't Italian. Pizza Hut isn't really Italian, but the roots are there. From the article:

JIANG: Salmon sushi started showing up all over Japan, especially at the cheap sushi restaurants, the ones with the conveyor belts. Bjorn realized salmon sushi had become a thing when a few years later, he was walking around Tokyo and he noticed the little plastic sushi replicas in the restaurant windows.

It may not have started that way, but it certainly is that way now.

But Gollum likes them rrrrraw and rrrriggling!!!!

Stick it in a stew?

I may have been wrong in my initial outrage. Salmon is just so good on its own… you get some crispy skin and a nice fatty flaky rich taste. Mmm.

Don't put that shit on us. We abuse it by grilling or baking it instead of smoking it like it deserves
