Water fly eggs known as Mexican caviar are a rare pre-Hispanic delicacy from lake regions. This high protein, keto-friendly ingredient is a prized, healthy superfood of ancient Aztec cuisine.
Finely chop the scallions and fresh cilantro; set aside for mixing.
In a medium bowl, whisk the eggs until completely blended, then gently stir in ahuautle, scallions, and cilantro until evenly combined.
Season the mixture with salt and black pepper, ensuring even distribution.
Heat olive oil over medium-low heat in a large nonstick skillet. Pour in the mixture and spread evenly to keep a uniform thickness.
Cook for about 4–5 minutes until the bottom is golden and set, then carefully flip and cook the other side for another 3–4 minutes; avoid high heat to prevent over-browning or drying.
Transfer to a plate, let rest for 2 minutes, then slice and serve warm as fritters or with fresh salsa.
