Aguachile

Aguachile differs from other lime-marinated shrimp dishes, such as ceviche, in that the marinating time is brief — just a few minutes — and the shrimp is served nearly raw, keeping a firm texture. It is typically served with cucumber, red onion, avocado and tostadas, alongside beer.

Sinaloa is Mexico's leading shrimp producer, which underpins aguachile's centrality in the state's cooking; the dish appears on the menu of nearly every Sinaloan seafood restaurant and has earned international recognition as one of the best-known expressions of Mexican seafood cuisine.

Some gastronomic accounts place a precursor of aguachile in the Sinaloa sierra, originally made with pounded meat, water and chiltepín pepper instead of seafood, with a later migration toward coastal towns — especially Mazatlán — where fresh shrimp replaced the dried meat. This lineage is repeated across several regional sources, but no single academic source documents it precisely; it should be read as an attributed tradition rather than an established fact.

Raw, peeled and cleaned shrimp is covered in a mixture of lime juice and green chile ground with water — the "chile water" that gives the dish its name — and left to sit only long enough for the surface of the shrimp to change color, without fully cooking through the way it would in a ceviche. It is served immediately with sliced cucumber, thinly sliced red onion and, depending on the region, avocado, alongside tostadas.
