There’s a line between Northern Baja and Southern California but nature knows no such borders and, neither does food nor the people. Baja’s food culture has long influenced Southern California and vice versa. The fish taco may be San Diego’s signature dish but it comes from Baja and the streets of Tijuana, sport nearly as many takes on the hot dog as on the taco. The Baja region has a wealth of distinctive ingredients from the ocean and the land such as: the fish of Popotla, San Diego’s sea urchins, the wine of the Valle de Guadalupe, California artichokes or the ubiquitous avocados on both sides of the border.,
