The bizarre evolution of sushi from fermented fish scraps to global luxury

Every Sushi Type Explained in 10 Minutes · 9:36 · Video: Food Explained · Watch at the source

In short: Sushi began as a preservation method where the rice was actually discarded. This video traces its transformation from 1800s street food to a billion-dollar industry, revealing how common ingredients like nori and spicy tuna rolls were born from waste.

The history of sushi is rooted in ancient techniques for preserving fish using fermentation. Interestingly, the original process involved throwing away the rice entirely. It wasn't until 1800s Tokyo that street carts began serving nigiri, and later innovations led to the creation of maki rolls.

Key distinctions are explored, such as why sashimi is technically not sushi. The video also highlights how various popular items were born from leftovers: nori was once discarded fishing net residue, toro was previously considered trash, and spicy tuna rolls were created using off-cuts too unappealing to serve individually.
