Ca cuong
From Wikipedia, the free encyclopedia
Cà cuống is the Vietnamese name for a giant water bug (Belostomatidae), specifically Belostoma indica, native to Southeast Asia. The bug's essence is harvested by collecting its liquid-producing sacs. That liquid is then placed in small glass containers.
The bug is scarce: demand for the extract is high. Most of the ca cuong essence on the market is therefore imitation, with the actual essence fetching a high price.
Cà cuống is typically used sparsely and eaten with cuốn by adding a drop to the dipping sauce.
The essence is in fact a pheromone produced by the male to attract mates.
