Yep. I’m a little too deep into sushi and it’s pretty funny that people will gatekeep ingredients.

The ingredients that Edomae chefs now use are extremely traditional. Essentially every single one was for food safety, not taste. Vinegar, wasabi, and sake in nikiri are all meant to prevent food-borne illness. The red rice vinegar used at high end restaurants was originally used because it was cheap. Fish is obviously readily available. Edomae chefs now use them because they prefer the taste— which I’ll agree with, I make it the same way— not because it’s sacrilege not to. Every one of the top chefs can tell you the history of sushi as a stall food meant to be accessible.

Even crotchety Jiro, who might chastise you for using soy sauce, deviates from tradition by using exclusively white vinegar and adding sugar. Yet the same gatekeepers love that guy (until you reach the super gatekeepers who are too cool for him because he got famous).

Sushi superiority is truly insane to me. I wonder if some assholes back then looked down on the “peasants” for trying to extend the shelf life of their food.

Sorry this comment is so long, I’m way too deep into this. It’s funny, two chefs I know are top five in Japan (thus, some would say, the world), respected beyond belief, and on my first visits they stayed well after close to talk to the dumb foreigner who wanted to improve his at home sushi. One doesn’t speak English and has one of his apprentices translate between us. I guess when you get far enough into sushi, you feel the need to ramble about it.
