Check out Maine who not only has a State Soft Drink,
but also a State Treat!
Yet, still no mention of California!
My search led me to these two sites Foodtimeline & Travel Gather, which both indicate California's State Fish is The Golden Trout.
Both sites give some examples of what California's State Food could be including some I thought were interesting like the Monte Cristo Sandwich,
which Foodtimeline says, "According to several articles published in newspapers and magazines, Monte Cristo sandwiches were first served in southern California and were very popular in the 1950s-1970s". Hmm, I did not know this. I would not think of this as California Cuisine.
Both Foodtimeline and Travel Gather also mention Chop Suey as a potential California State Food.
Foodtimeline says "The stir-fried hash was invented, according to tradition, in a San Francisco restaurant during the wee hours one morning when a rowdy group of holidaying diners would not hear of the Chinese cook's plea that he had no food."
So what should California's State Food be? I think there are too many good things to choose from to pick just one!
