Ahuautle, often referred to as ‘Mexican caviar’, is a traditional food from Mexico that consists of the eggs of aquatic insects, primarily from the Axayacatl (water fly). These eggs are harvested, dried, and then often pan-fried. The result is a crunchy, nutritious food that’s high in protein. Ahuautle has been a part of the local diet in Mexico for centuries, particularly in and around Mexico City (the former Aztec capital of Tenochtitlan), where these insects are abundant.
