Aguachile is a simple dish originating from the Mexican state of Sinaloa. It is a type of Mexican ceviche that (in its most classic version) consists of fresh raw shrimp, cucumber, red onion, lime juice, and water-pulverized chilis, giving the dish its name.

Unlike most ceviches, aguachile is served immediately after coating the shrimp in lime juice, so it is very important that the shrimp is as fresh as it can be. Aguachile is commonly accompanied by avocado and tostadas, while the beverage of choice is usually beer or tequila.

There are also versions of aguachile prepared with octopus and scallops, but those versions are not traditional.
