I remember my horror when presented with a deep-fried roll in a sushi place in Reno. It may have even been this particular example from that very place. I'm pretty sure I've been there.
Anyway, it was delicious. And wrong. Which somehow made it better, and then worse. But then I thought - do I really want the sort of raw fish they can get in Reno, Nevada? Actually, you can get proper sushi in reno - but there are or were a number of places that served no raw fish at all. You really had to think of it as a completely different thing - with a lot of Mexican and Central American flavors added into the mix.
Try it if you get the chance.
This is the one I bought recently: https://www.amazon.com/dp/B00025H2PY/
I buy in bulk because I also use it around my yard as pest control - it's basically microscopic shards of glass and this cuts up a bugs exoskeleton when it crawls over it. Anyway, you can use any food grade diatomaceous earth though. I buy whatever brand is cheap as long as reviews are good. Food grade, not pool grade because that's poison. I just mix 1 tbsp in a glass of water and down it (you might want to start with 1tsp and work up to avoid GI issues). Tastes like chalk.
If you're the type of person who can't handle drinking chalk water, then you can buy silica tablets instead. I used to take the NOW brand but switched to DE because it's a lot more cost effective.
