This is from Sinaloa. Specifically from the Pacific coast, from Mazatlan and Culiacan and the marisquerias along the malecon where the boats come in at dawn and the seafood is on the counter by ten in the morning. Sinaloa is Mexico's seafood state. Most of the country's farmed and wild-caught shrimp comes from here. The marisco tradition is not a trend. It is the daily economy of the coast.
A tostada de mariscos in Sinaloa is not the small, dainty thing you find on appetizer menus in other states. It is lunch. One tostada, piled so high the seafood spills over the edges, eaten standing at the counter or at a plastic table set up under a tarp by the water. The seafood is already cooked, shrimp poached briefly, octopus simmered slow, crab picked clean, then dressed in lime, onion, tomato, cilantro, and the trinity that makes this dish unmistakably sinaloense: catsup, Maggi, and salsa inglesa. That combination tells you immediately what coast you are on.
My mother never made these. Sinaloa was not her food. But I went to Mazatlan in my second year of the 32-state project and I sat at a marisqueria called La Puntilla for four hours one afternoon, watching the cook scare the octopus in the boiling pot, lifting it three times before letting it sink. She told me the wine corks her abuela dropped in the water were not superstition. They were technique. I have done it her way ever since.
The seafood has to be good. There is nowhere to hide on a tostada. Si no conoces el mercado, no conoces la cocina.
The Sinaloa coctelero tradition, the marisquerias built around catsup-Maggi-Worcestershire seafood cocktails and tostadas, took its modern form in the mid-20th century as the state's commercial shrimp industry exploded after World War II. Sinaloa accounts for the majority of Mexico's shrimp production, both farmed and wild-caught, and the marisqueria emerged as the casual format that allowed coastal cooks to serve the daily catch without the overhead of a sit-down restaurant. The use of bottled European-style condiments, Maggi (Swiss-German), Worcestershire (English), and ketchup, alongside indigenous ingredients like lime, chile, and cilantro reflects the cosmopolitan port history of Mazatlan, which was a major Pacific trade hub from the 19th century onward.
The technique, the tradition, and the story behind every dish.

Equipment Needed
- •Large heavy-bottomed pot for cooking the octopus
- •Slotted spoon or kitchen spider
- •Wide glass or ceramic mixing bowl (do not use metal with the lime)
- •Sharp knife for slicing the octopus and dicing the vegetables
Instructions
- 1
Cook the octopus
Bring a large pot of water to a rolling boil. Add the quartered onion half, the head of garlic, the bay leaves, the salt, and the wine corks if you are using them. Hold the octopus by the head end and dunk the tentacles into the boiling water three times, lifting them out between each dunk. The tentacles will curl tight. This is the scaring technique they use in the Mazatlan marisquerias and it tenderizes the flesh as it cooks. Now lower the whole octopus into the pot. Reduce to a steady simmer and cook 35 to 40 minutes, until a knife slides into the thickest part of a tentacle without resistance. Pull the octopus out and let it cool before slicing into bite-sized pieces.
The wine corks are not folklore. The natural enzymes in cork are believed by Sinaloa cooks to help tenderize the octopus. Whether the science holds, the technique has been passed down for generations and the octopus comes out tender. No me vengas con atajos. - 2
Poach the shrimp
While the octopus cools, toss the reserved shrimp shells into the same cooking liquid and let them simmer 5 minutes to build a quick broth. Strain. Return the broth to a gentle simmer, salt it well so it tastes like the sea, and slide the shrimp in. Cook 90 seconds to 2 minutes only, until they just turn opaque and curl loosely. Pull them with a slotted spoon directly into a bowl of ice water. Overcooked shrimp turns rubbery and there is no fixing it. Drain and pat dry. Cut each shrimp into two or three bite-sized pieces.

Dress the seafood in lime
In a wide glass or ceramic bowl, combine the chopped octopus, the shrimp pieces, and the crab meat. Pour the lime juice over and toss gently. Season with a generous pinch of salt. Let it sit 10 minutes in the refrigerator. The lime is not curing this seafood, everything is already cooked, but it brightens and seasons the meat the way a marinade does. The seafood should taste alive, not pickled.
- 4
Build the dressing
Add the diced white onion, the diced Roma tomatoes, the cilantro, the minced serrano, and the diced cucumber to the seafood bowl. Stir in the cocktail sauce, Maggi sauce, and Worcestershire. This combination of catsup, Maggi, and salsa inglesa is the Sinaloa signature, the trio that defines a Mazatlan marisqueria coctel. Taste for salt and lime. The mixture should be tangy, slightly sweet from the catsup, savory from the Maggi, with the heat of the chile coming up at the end. Fold in the diced avocado last so it does not break down.
Do not skip the Maggi. Sinaloa marisquerias use it the way other states use salt. It carries an umami depth that nothing else replaces in this dish. - 5
Assemble the tostadas
Spread a thin layer of mayonnaise across each crisp tostada. The mayonnaise is the glue. It also keeps the tostada from soaking through too quickly. Mound a generous heap of the seafood mixture on top, enough that it spills over the edges. This is a meal-sized tostada, not an appetizer. In Mazatlan, one tostada de mariscos is lunch.
- 6
Serve immediately
Top each tostada with a few slices of avocado and a shake of Salsa Huichol or Valentina. Serve with lime wedges on the side. Eat with both hands, standing up if you have to. Tostadas de mariscos do not wait. The crispness of the tortilla against the cold seafood is the whole point. Asi se hace y punto.
Chef Tips
- •Buy the freshest shrimp you can find, ideally Pacific white shrimp from Sinaloa or Sonora if you have access to a Mexican fish market. Frozen shrimp from a reliable source is better than questionable fresh shrimp. Smell it before you buy it. Clean ocean, nothing else.
- •If you cannot find whole octopus, pre-cooked octopus from a good Mediterranean or Mexican market is an honest shortcut. It is not a compromise on flavor, only on technique. Skip steps 1 and the first half of 2 if you go this route.
- •The crab matters. Use real lump crab meat, not the imitation surimi. If lump is out of your budget, claw meat is the next best thing. Surimi has no place on a Mazatlan tostada.
- •Mexican limes, the small green ones, give the right brightness. Persian limes will work but you will need a few more. Bottled lime juice is not lime juice. Do not use it.
Advance Preparation
- •The octopus can be cooked one day ahead, sliced, and refrigerated. The flavor only improves overnight.
- •The shrimp can be poached up to 6 hours ahead and held on ice in the refrigerator.
- •The seafood mixture should be assembled no more than 2 hours before serving. Past that, the lime starts to break down the texture and the avocado oxidizes. Build the tostadas at the moment of eating, never before.
