Today, ingredients such as Parmigiano-Reggiano cheese and extra-virgin olive oil are staples in American foodie kitchens. But several decades ago, they were still relatively rare in the United States.

Products like these—artisan, high-quality, and often imported—became popular in American culture thanks, in part, to the California Food Revolution. And the California Food Revolution succeeded thanks, in part, to a couple Italian guys who owned a supermarket in Sacramento: the Corti brothers. Seventy years later, visitors can still visit the last remaining Corti grocery.
