So, after posting my ingredient wishlist, I got some comments and emails that have lead me to some potential sources. I now have a reason to get up early and hit the farmer's market-we sort of slacked off when we moved further away and grew more of our own vegetables.
I am also happy to say that we did find a good source for sushi grade fish. Matt went to H Mart (over off Rolling Rd, for you locals) and they had sashimi grade salmon. So he brought some home and we made raw sushi rolls! I don't think they always have it in, but they did yesterday. Very exciting! So I can cross that off the list. If you are interested, here is a blog post I found about the safety of raw salmon.
