Fall leaves are turning and the breeze is cooling down, calling all soup lovers to fill up their bowls. An American favorite is the classic Split Pea Soup. In spite of its mushy demeanor, the traditional recipe holds quite a solid reputation—one that can be attested to by travelers who have passed through Buellton, California, for more than eighty years to savor the signature at Pea Soup Andersen’s. This old reliable may soon become green with envy as new and creative variations are appearing in restaurants across the country.
