Etymology

Origin of natto

First recorded in 1870–75; from Japanese, from na(t)- (ultimately from Middle Chinese; cognate with Cantonese naap, Mandarin “to bring into, receive”) + “bean” ( see bean ( def. ))

Explanation

Natto is a sticky, strong-flavored Japanese dish made from fermented soybeans, often served over rice and commonly enjoyed at breakfast. Natto is a traditional Japanese dish that dates back over 1,300 years. It is made using a special fermentation process that gives it its signature stickiness and pungent aroma. While its unique smell and gooey texture might take some getting used to, natto is highly nutritious and packed with protein, vitamins, and probiotics, making it a healthy and flavorful addition to a meal.
