In Spanish tapas, what is a salpicón de marisco made primarily from?

Salpicón de marisco is primarily made from mixed seafood dressed as a cold Spanish salad or tapa.

Typical versions combine seafood such as prawns, mussels, octopus, or crab with onion, pepper, and sometimes tomato. The ingredients are chopped into bite-sized pieces and dressed with olive oil and vinegar, creating a bright preparation that is usually served chilled or at room temperature.

The exact seafood depends on the coast, season, and household recipe. For that reason, one particular shellfish is not the canonical answer. The defining idea is a seasoned mixture rather than a single seafood ingredient.

Salpicón is related to other Spanish and Latin American preparations bearing the same name, but recipes are not identical across the Spanish-speaking world. In tapas bars, it is valued as a refreshing contrast to fried dishes and heavier cured meats.
