What does the word “sushi” mean?
You may be surprised to find that the word “sushi” doesn’t mean raw fish; it is an outdated Japanese term that literally means “it’s sour.” It refers to vinegared rice, commonly topped or mixed with fish or vegetables. Over 600 years ago, rice and raw fish were fermented together to create what is now known as narezushi. In later years sushi chefs added vinegar to the rice to increase the dish’s sourness. The recipes evolved to become what we know as sushi today, but some restaurants in Japan still serve forms of the original narezushi.
