Black clam ceviche is one of northern Peru’s most distinctive seafood dishes, especially associated with Tumbes and Piura. It is made with black clams, lime juice, red onion, ají limo, and cilantro, creating a bold ceviche with a deep briny flavor and a characteristic dark color. Traditionally the clams are used raw, but at Recetas123 we steam them until they open and chill them before mixing: lime juice does not make raw shellfish safe.
Because the shellfish is delicate, this ceviche is prepared and served immediately. In northern Peru, it is commonly paired with plantain chips, toasted cancha corn, and sometimes boiled cassava or sweet potato. Its rich flavor makes it very different from classic white-fish ceviche.

Peruvian Black Clam Ceviche
- Prep Time: 20 minutes
- Cook Time: 10 minutes
- Total Time: 1 hour
- Yield: 4
- Category: Main Course
- Cuisine: Peruvian
Ingredients
- Fresh, closed black clams in the shell, enough to yield about 500 g of meat
- A little water for cooking the clams
- 120 ml fresh lime juice (½ cup)
- 180 g red onion, thinly sliced (1 medium onion)
- 20 g ají limo, seeded and finely chopped (1 medium pepper)
- 15 g chopped fresh cilantro (¼ cup)
- 5 g salt (1 teaspoon)
- 2 g ground black pepper (½ teaspoon)
- 10 g minced garlic (2 cloves)
- 150 g plantain chips (2 cups)
- 120 g toasted cancha corn (1 cup)
- 300 g boiled sweet potato, sliced (2 medium sweet potatoes)
- 1 lime, cut into wedges
Preparation
- Cook the clams, discard any clams that are broken or open. Place the rest in a pot with a little water, cover, and steam them until they open; throw out any that do not open.
- Chill the clams, remove the meat from the shells, strain the liquid they released, and refrigerate the meat and liquid until well chilled.
- Soften the onion, place the sliced red onion in cold water for 5 minutes. Drain it thoroughly and combine it with the ají limo, cilantro, garlic, salt, and black pepper.
- Make the ceviche, add the cooked, chilled black clams and their liquid to the onion mixture. Pour in the fresh lime juice and toss gently for a few seconds, taking care not to break the clam meat.
- Serve immediately, divide the ceviche among chilled plates and serve with plantain chips, toasted cancha corn, and slices of boiled sweet potato. Bring it to the table right away to preserve the clams’ fresh flavor and natural texture.
Chef’s Tips
- Buy black clams only from trusted suppliers and make sure they are fresh and properly chilled.
- Keep the cooked clams in the refrigerator until you assemble the ceviche.
- Do not leave the clams in lime juice for long; this ceviche should be mixed and served almost immediately.
- Strain and save the liquid the clams release as they cook, as it gives the ceviche much of its defining flavor.
- Use ají limo with moderation so it enhances rather than overwhelms the shellfish.
Traditional Variations
In northern Peru, some versions include a small amount of diced tomato or corn kernels. Others are served with boiled cassava instead of sweet potato. The most representative version keeps black clams, lime, red onion, ají limo, and cilantro as its foundation.
How to Serve
Serve black clam ceviche very cold in individual plates or a small shared serving dish. Pair it with crisp plantain chips, toasted cancha corn, and boiled sweet potato. A cold lager beer or chilled chicha morada complements its bold briny flavor.
Recommended Accompaniments
- Green plantain chips.
- Toasted cancha corn.
- Boiled sweet potato.
- Boiled cassava.
- Chilled chicha morada.
A Little History
Black clams are closely associated with the mangrove ecosystems of northern Peru. Their unique flavor comes from that coastal environment, which is why this ceviche has a very different identity from white-fish ceviche.
In Tumbes, black clam ceviche is one of the most recognized dishes of regional cuisine. It is usually prepared with simple ingredients so the shellfish remains the center of the plate.
Frequently Asked Questions
In this recipe, yes. Traditionally they are used raw, but lime juice alone does not remove the risk of raw shellfish, so we steam them until they open (discarding any that do not open), chill them, and then mix them with the lime juice, onion, chili, and cilantro. Always buy them from an authorized supplier and keep them refrigerated.
It should rest for very little time. Mix the ingredients and serve immediately, or no more than 2 to 3 minutes later. Black clams have a delicate texture and an intense briny flavor that are best when the lime juice has not cured them for too long.
It is not recommended. Fresh lime juice provides the bright acidity, aroma, and clean flavor that are essential to authentic Peruvian ceviche. Bottled juice often contains preservatives or has a different level of acidity that can alter the clams’ natural taste.
Keep them refrigerated between 0 and 4 °C or 32 and 39 °F in a clean container, loosely covered with a damp cloth. Do not soak them in fresh water or leave them at room temperature. Prepare them on the day you buy them for the best quality and safer handling.
