Fish Tacos
The popular version of fish tacos—as opposed to those made with grilled fish, native to Mexico—is believed to have originated in Southern California, where there is a strong Mexican influence on cooking and plenty of coastline for reeling in fish. They are garnished with a variety of piquant salsas and relishes and usually crema, the Mexican equivalent of sour cream; these are topped with a sour cream–based sauce, spiked with smoky chipotle chiles.
