Sushi Was Invented in Southwest Asia
possibly along what is now known as the Mekong River. The term sushi comes from an archaic grammatical form no longer used in other contexts; literally, sushi means "sour-tasting", a reflection of its historic fermented origins. The oldest form of sushi in Japan, narezushi, still very closely resembles this process, wherein fish is fermented via being wrapped in soured fermenting rice.
is a Japanese food consisting of cooked vinegared rice sushi-meshi combined with other ingredients : seafood, vegetables and sometimes tropical fruits. Ingredients and forms of sushi presentation vary widely, but the ingredient which all sushi have in common is rice (also referred to as shari or sumeshi.
All sushi has a base of specially prepared rice, complemented with other ingredients.
The black seaweed wrappers used in makimono are called nori. Nori is a type of algae, traditionally cultivated in the harbors of Japan. Originally, algae was scraped from dock pilings, rolled out into thin, edible sheets, and dried in the sun, in a process similar to making rice paper. Today, the commercial product is farmed, processed, toasted, packaged, and sold in sheets.
