Vacationing in San Francisco, CA, I took a walking tour called "Emperor Norton's Fantastic San Francisco Time Machine". The tour guide was in character for the entire tour as one of San Francisco's beloved citizens of the late 1800's named Emperor Norton the First. While standing in front of one the city's ice cream parlors; he described a ice cream sundae served there that was named for him but had been discontinued. He gladly gave us the recipe and I hope that you enjoy it as much as I do. I apologize for the picture, but I am sure you get the idea.
