Peruvian ceviche de muy muy is a traditional dish from Peru’s northern coast, made with muy muy, a tiny sand crab that lives on the beaches of Piura and Tumbes. It’s briefly marinated in lime, chile, and onion, following the classic coastal ceviche technique.
Muy muy is gathered straight from the wet sand as the wave pulls back, a traditional activity on beaches like Colán and Máncora. Because of its small size and bold flavor, this ceviche is prized as something distinct from the more familiar fish ceviches.

- 30 g ají limo or ají amarillo picado (2 tablespoons)

Preparation

- Finish and serve, add the onion and cilantro, adjust the salt, and serve immediately with sweet potato, corn, or toasted corn nuts.
Chef’s Tips
- Use very fresh ingredients; muy muy is meant to be eaten the same day it’s gathered.
- Adjust the chile and salt at the end, since muy muy has its own strong flavor.
- Don’t let it marinate too long; unlike fish ceviche, muy muy is served almost immediately.
Traditional Variations
In some northern coves, muy muy is combined with black clams or other small shellfish for a mixed small-seafood ceviche.
There’s also a concentrated “tiger’s milk” style version, where the marinade liquid is served on its own as a drink, very popular in the region.
How to Serve
Serve freshly made and cold, in a small dish or glass, alongside sweet potato, corn, or toasted corn nuts. It’s a common find at beach stalls along Peru’s northern coast.
Recommended Pairings
- Boiled sweet potato
- Corn on the cob
- Toasted corn nuts (cancha)
