Tostada de Mariscos

A tostada de mariscos is a Mexican seafood tostada, consisting of a crisp, fried or toasted corn tortilla topped with a chilled mixture of fresh seafood, typically shrimp, octopus, and fish, marinated in lime juice and seasoned with chili, salt, and cilantro. The dish originates from coastal regions of Mexico, particularly the Pacific coast, where abundant seafood is prepared in a ceviche-like style.

Key ingredients include fresh raw seafood "cooked" in citrus juice, diced tomato, onion, cucumber, and avocado, served on a crunchy tostada base. A great version is distinguished by the freshness and quality of the seafood, the balance of acidity from the lime, and the contrast between the cold, tangy topping and the crispy, warm tostada. The seafood should be tender and opaque, not mushy, and the flavors bright and well-integrated.

Regional variations abound. In Puerto Vallarta, Mexico, the tostada de mariscos is a staple. Mark Wiens, a prominent food creator, visited the venue Latia Nanya in Puerto Vallarta, where he highlighted their version as a standout example of the dish. Variations may include the addition of salsa negra, a dark, savory sauce, or the use of different seafood like scallops or crab. Some versions incorporate mayonnaise or crema for richness, while others keep it lighter with just citrus and herbs. The dish is often served with lime wedges and hot sauce on the side, allowing diners to customize the heat and acidity to their preference.
