Peruvian ceviche de muy muy is a dish from Peru’s northern coast, made with muy muy, a small crustacean that burrows in the sand of the beaches of Piura and Tumbes, combined with lime, chili, red onion, and cilantro.
Traditionally, some people prepare it with raw muy muy, simply mixed with lime. At Recetas123 we offer an adaptation for food safety: the muy muy is cooked first until its flesh is completely opaque, chilled quickly, and only then mixed with the other ingredients. Lime adds flavor, but it does not cook raw shellfish or make it safe.
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.

Description
Peruvian preparation featuring muy muy limpio, adapted for a home kitchen with clear measurements.
Ingredients
For cooking the muy muy
- 800 g fresh muy muy
- Water for cooking
- Salt for the cooking water
- Ice water for chilling
For the ceviche
- 180 ml freshly squeezed lime juice (3/4 cup)
- 200 g red onion, thinly sliced lengthwise (1 large onion)
- 30 g ají limo or ají amarillo, chopped (2 tablespoons)
- 15 g chopped cilantro (1/3 cup)
- Salt, to taste
For serving
- Boiled sweet potato, corn, or cancha (toasted corn), to taste
Preparation
- Clean the muy muy, keep the muy muy refrigerated until you use it. Rinse it in a bowl of cold water, changing the water until all the sand is gone, and discard any that smell bad. Then wash the utensils and surfaces that touched the raw shellfish.
- Cook the muy muy, bring plenty of salted water to a boil, add the muy muy, and cook it until it changes color and its flesh is completely opaque and firm.
- Chill quickly, drain it and transfer it right away to the ice water until completely cold. Drain it well and keep it in the refrigerator until you make the ceviche.
- Make and serve the ceviche, just before serving, place the cooked, chilled muy muy in a bowl, season it with salt and the chili, stir in the lime juice, and mix gently. Add the onion and cilantro, adjust the salt, and serve immediately with sweet potato, corn, or cancha.
Chef’s Tips
- Buy very fresh muy muy and keep it refrigerated until you cook it.
- Cook it until the flesh is completely opaque and firm, and chill it right away in ice water.
- Add the lime just before serving; the ceviche does not need any marinating time.
- Adjust the chili and salt at the end, since muy muy has its own strong flavor.
Traditional Variations
In some northern coves, muy muy is combined with black clams or other small shellfish for a mixed small-seafood ceviche. If you make it this way, cook that shellfish too before mixing it in.
How to Serve
Serve freshly made and cold, in a small dish or glass, alongside sweet potato, corn, or cancha. Once mixed with the lime, serve it right away.
Recommended Pairings
- Boiled sweet potato
- Corn on the cob
- Cancha (toasted corn)

Muy muy is a small crustacean that burrows into the sand almost instantly as a wave recedes, making it something of a game to catch for visitors to Peru’s northern beaches. It’s traditionally said to have aphrodisiac properties in coastal folk culture.
Frequently Asked Questions
It's a coastal dish from northern Peru made with muy muy, a small crustacean that burrows in beach sand. In this recipe the muy muy is cooked and chilled before being mixed with lime, onion, chili, and cilantro.
For food safety. Lime adds flavor, but on its own it does not cook raw shellfish or remove its risks. That's why we cook it until its flesh is completely opaque and firm, chill it quickly, and only then make the ceviche.
Muy muy is harvested on beaches in northern Peru, such as Piura and Tumbes, and sold fresh in local markets in those areas. Outside those regions it's hard to find, making this a very regional recipe.
If muy muy isn't available, a similar ceviche can be made with small shrimp or black clams, cooked first in the same way, though the characteristic flavor and texture of muy muy won't be exactly replicated.
