Ham and bean soup is one of the oldest dishes in American home cooking — a direct descendant of the bean pottages that sustained European peasants for centuries and crossed the Atlantic with the first settlers. In NE Ohio farm families, where a whole smoked ham was an event, the leftover bone was never wasted. It went into a pot of beans, and it fed the family for days afterward. Mary April made this the way her mother made it, and her mother before that.
