About this recipe
Crispy corn tostadas topped with shredded smoked marlin, avocado, tomato and red onion. Speciality of Mazatlán and the Sinaloa Pacific coast.
History & Origin
Smoked marlin tostadas are one of the most iconic snacks of Mazatlán, the most important coastal city of Sinaloa state, and the Mexican Pacific coastline in general. Striped marlin (Kajikia audax) and black marlin (Istiompax indica) are deep-sea fish abundant in the Pacific off the coasts of Sinaloa, Nayarit and Baja California Sur, fished artisanally by generations of Sinaloa fishermen. Mazatlán smoked marlin has a history going back to at least the 19th century, when port fishermen began smoking surplus catch to preserve it during months of lower fishing. Cold or hot smoking with fruit wood or mangrove gives the marlin a deep, salty and slightly sweet flavour that distinguishes it from any other smoked fish in the world. Marlin tostadas emerged as a way to use shredded smoked marlin: placed on a crispy corn tostada, topped with sliced avocado or guacamole, diced tomato, red onion, coriander and a squeeze of lime. This quick assembly became the favourite snack of Sinaloan ports, eaten at all hours in seafood restaurants, tostada stalls and beach eateries. Today, Mazatlán smoked marlin is exported throughout Mexico and to Mexican community markets in the USA. Marlin tostadas are also made with fresh marlin ceviche marinated in lime and chilli, popular during sport fishing season.

Method
- 1
Shred 300g smoked marlin by hand or with a fork, checking for any bones. If the marlin is very salty, rinse briefly in cold water and pat dry with kitchen paper.

💡 Smoked marlin is available at specialist fishmongers or quality seafood shops.
- 2
Dice 2 medium tomatoes small, slice half a red onion into fine strips, slice 1 serrano chilli into thin rings and chop fresh coriander to taste. Mix in a bowl with juice of 2 limes and salt.

💡 For less heat, remove the seeds and veins from the serrano.
- 3
Mash or slice 2 ripe avocados. Season with salt, lime juice and a pinch of pepper. Set aside.

💡 For a guacamole version: mash the avocado with a fork and mix with the other chopped ingredients.
- 4
Warm 8 corn tostadas on a griddle or in the oven at 170°C for 5 minutes until extra crispy.

- 5
Assemble the tostadas: spread avocado, add the shredded marlin, top with the tomato and onion mix, finish with hot sauce and a lime wedge. Serve immediately.

💡 Tostadas soften quickly, so assemble just before serving.
