Traditionally eaten by hand in Japan, this dish has roots in a fermented rice preservation technique that likely began along the Mekong River basin in what is now Thailand, Laos, Cambodia and Vietnam. Which dish is now a global staple thanks in part to conveyor-belt restaurants?

Question

Accepted Answer

Sushi. Modern nigiri sushi, a slice of raw fish on hand-pressed vinegared rice, dates only from 1820s Edo (Tokyo), but the underlying rice-and-fish fermentation technique is a millennium older. Norway's push to sell salmon for raw consumption in the 1980s created what is now one of the most familiar sushi toppings.
