This extravagant recipe is said to date back to the California Gold Rush. After striking lucky in Placerville (then known as Hangtown), a prospector went to a local hotel and demanded the most expensive dish money could buy: an omelet filled with bacon and oysters. The eggs had to be carried carefully to the remote mining town, the bacon was shipped from the East Coast, and the oysters were sourced from more than 100 miles away. You can still order variations on the legendary dish at a handful of San Francisco and Placerville restaurants today.
