Chocolate Clams: A Guide to Baja’s Obsession-Worthy Seafood
Updated: Sep 5
One of the world’s best bites comes in a decidedly plain package: a large, brown shell. The almeja chocolate, or chocolate clam, is found along the Baja Peninsula and Sea of Cortez. It’s named for the cocoa-like color of its shell and not for its flavor, we promise.
Chocolate clams refer to two species of edible bivalves, M. squalida and M. aurantiaca, which live in the sandy waters of the Sea of Cortés and along the Pacific Coast of the Baja Peninsula. Historically, they have been a humble food source for coastal Mexican residents and fishing families, who most often roast them right in the sand on the beach or crack them open and enjoy them in raw, ceviche-like preparations. In recent decades, as regional Mexican cuisine has swelled in popularity, so have these pretty, mildly-flavored shellfish.
To say we’re obsessed would be an understatement.
Whenever we visit Baja—which is often—a chief priority is getting our hands on fresh chocolate clams. But the Baja’s love of chocolate clams is nothing new. In fact, there are archaeological shell middens around Loreto, Baja California Sur, show the brown bivalves have been part of locals’ diets since pre-Hispanic times.
While I’m not sure how folks ate the clams hundreds of years ago, they’re now served raw with a slew of toppings or cooked over a fire. In fact, almejas tatemadas, or fire-roasted chocolate clams, are recognized by the Mexican government as a traditional dish of Loreto.
Note: Experts recommend waiting till children are at least 5 years old before introducing them to raw seafood.
Where to Find Chocolate Clams
Loreto is a great place to start if you’re wanting to try chocolate clams. This is, after all, the birthplace of almejas tatemadas, and you’ll love the experience of watching clams cooked in a dramatic beachside fire. Traditionally, the clams are arranged on a bed of gravel, covered, and topped with dry local brush called romerillo or chamizo. The brush is burned, surrounding the clams with intense heat and aromatic smoke. Hotel Loreto Palmar has a complete guide to how to enjoy this delicacy.
Of course, chocolate clams are found outside of Loreto, too. You can find them in La Paz, Cabo San Lucas, and as far north as Ensenada. Be prepared to be picky, though. If you’re wanting to experience “live clams,” make sure to ask whether the clams are fresh (not frozen).
More Southern California restaurants are starting to feature chocolate clams on their menu, but most often they’re frozen … and just not the same.
Sur Cabo, the beachside restaurant that's part of Bar Esquina in Cabo San Lucas, features an upscale preparation of raw chocolate clams with jicama, cucumber, red onion, fresno chili, tiger milk, and basil.
Bismarkcito, the open-air seafood mecca located alongside La Paz's malecón, or boardwalk, is a no-frills destination for raw chocolate clams. Here you can order them raw, stuffed, or steam.
Also in La Paz on the malecón, Mariscos El Molinito features fresh preparations of the chocolate clams.
La Palapa in Loreto has two styles of chocolate clams: raw and Palapa style.

How to Eat Them
In our eyes, the simplest preparation is also the best. Enjoy these babies raw and on the half shell. When exceptionally fresh and handled properly, chocolate clam meat can be served with lime, salt, and a favorite chile-based salsa. The meat is firmer and more substantial than that of a delicate oyster, making it a satisfying bite of intensely marine flavor. One of the most magical experiences we’ve had is pulling clams right out of the water off the coast of Loreto and eating them fresh in the panga, or skiff.
And if you want the quintessential Loreto experience, order them tatemadas. The traditional method is wonderfully elemental. Once cooked, the blackened shells are brushed clean and opened. The meat is commonly eaten with salsa, lime, salt, cilantro, and tortillas. The tortilla is more than a side dish: it makes a perfect edible plate for the smoky clam and its juices.
For first-timers, try one raw if the restaurant or vendor specializes in fresh clams, then order a tatemada to experience the signature preparation. The contrast is the point: raw, the clam tastes clean, briny, and distinctly of the Sea of Cortez; cooked over a wood or brush fire, it becomes tenderer and takes on a deep, smoky character.
Above all, ask where the clams came from. Baja’s chocolate clam is a remarkable regional ingredient, but its future depends on allowing depleted beds to recover. Choosing legally harvested clams—and respecting current closures—is part of enjoying the dish responsibly.
