A Vietnamese staple ingredient,rice paper (banh trang),soaked in water to rehydrate instead of being rolled, then dipped in various sauces. This simple way of eating,"banh trang nhung nuoc"（bánh tráng nhúng nước）」が、2026年初頭からベトナムのSNSで一気に広がった。ベトナム大手紙Thanh Niênfeatured it, and a post by a food creator with 400,000 followers drew nearly 7 million reactions, turning it into a viral hit centered on Gen Z.
So what exactly is "rice paper soaked in water"?
The method is extremely simple. Stack several sheets of rice paper, dip them in water, and let them soften. Once they take on a chewy, dough-like texture, dip them in a sauce of your choice and eat. You don't roll fillings inside like fresh spring rolls, nor do you grill them. It is a pared-down snack for savoring the texture of the rice paper itself.
The key to the flavor is the dipping sauce. From salty ones like salted plum paste, shrimp paste, and soy sauce, to sweet ones like condensed milk and coconut juice, what you dip it in dramatically changes its character. Some posters have said, "It's like eating banh uot (steamed rice noodles), chewy and pleasantly salty."
Why did it catch fire in 2026?
The reason for the hit lies in its sheer simplicity. All you need are ingredients already at home. No special equipment or skill required, and anyone can copy it in minutes. It pairs well with the "I tried it" culture of social media and spread rapidly through short-form videos.
Opinions, however, are divided. Some cooler comments say, "In the end it's all about the sauce; the thing itself is unremarkable," and there is no denying that the novelty has run ahead of the substance. It isn't entirely new as a dish, and plenty of rural residents attest that "we've eaten something similar for ages." If anything, many welcome the spotlight it has thrown on rural rice paper producers.
How can Japanese travelers enjoy it?
Vietnamese rice paper is available at supermarkets and Asian grocery stores in Japan too. The fun of this trend is that you can try it at home before or after your trip. For salty, go with plum or soy sauce; for sweet, condensed milk. See how far you can push the flavor range with the seasonings on hand. If you spot it at a stall, comparing what sauces are served locally is another pleasure.
The essence of the buzz: a renewed spotlight on the ingredient
Not a flashy look, but a single way of eating a commonplace ingredient can spread this far. Just like the one-handed banh mi videos and pho's global rankings, Vietnamese food reaches the world along the extension of ingredients and everyday life. Banh trang nhung nuoc is one lighthearted example of that.
