When April's rainy season arrives, Tày families head into the hills looking for ant nests on specific tree species, carefully extracting the white eggs inside, mixing them into rice flour, wrapping the mixture in leaves, and steaming it. This plain-looking snack carries a piece of foraging wisdom that makes outsiders wince at the description -- and then rave about it once they've tasted it.
Cross-confirmed by Vietnamese Wikipedia, local media, and mainstream media as a seasonal Tày snack
Vietnamese Wikipedia has a standalone entry for this snack. Cao Bằng's official provincial party newspaper and mainstream news outlet VietNamNet's Ethnicity and Development channel cross-confirm it as a Tày tradition: black ant eggs are gathered every April and May, mixed into rice flour, wrapped in leaves, and steamed. It has a dense, chewy texture with a distinctive aroma, and it's a highland specialty that many city dwellers make a special trip to seek out.
Honest clarification: Bắc Kạn and Hà Giang provinces also have this specialty -- it isn't unique to Cao Bằng
It has to be said honestly that sources explicitly record this snack as "also a specialty of Bắc Kạn and Hà Giang provinces" -- it isn't unique to Cao Bằng, and this entry honestly discloses this cross-province overlap rather than overstating it as a Cao Bằng original. Within Cao Bằng province, there's no dispute limiting its origin to a specific district; the tradition of gathering black ant eggs in April and May is common across Tày communities province-wide, and it's also made and sold in the city. Its exact founding period is described only in general terms as "originating from the early era of rice-growing civilization," with no precise historical record -- this entry doesn't adopt that as settled fact.
How to Eat It Like a Local
- Visit a Tày community in Cao Bằng in April or May for a chance at a version made with freshly gathered, freshly steamed eggs.
- The traditional way to eat it is on its own while hot, or paired with a cup of hot tea to balance the texture.
- It's also made and sold in the city, so visitors who miss the season can still find it at the market.

- Within Cao Bằng province, there's no dispute limiting its origin to a specific district -- the tradition is found across Tày communities province-wide.

Bite into the ant-egg cake and the dense rice flour carries the subtle, distinctive aroma of the eggs within. That flavor might be found in Bắc Kạn or Hà Giang too, but the foraging eye the Tày people have passed down through generations remains the hardest part of this snack to replicate.
